Understanding Internet Security Threats
by: Ki Grinsing
Understanding The Internet Security Threats That Are Commonly Introduced Into The Wild Internet
When we are surfing the internet at home or at the office, the computer is exposed to the wild internet where many types of threats might cause the computer to function incorrectly. Unlike a large scale network infrastructure of a corporate that has proper information security management, your computers at home might be vulnerable to the threats.
Definitions of Programmed Threats
Computers are designed to execute instructions one after another. These instructions usually do something useful—calculate values, maintain databases, and communicate with users and with other systems. Sometimes, however, the instructions executed can be damaging or malicious in nature. When the damage happens by accident, we call the code involved a software bug. Bugs are perhaps the most common cause of unexpected program behavior.
But if the source of the damaging instructions is an individual who intended that the abnormal behavior occur, we call the instructions malicious code, or a programmed threat. Some people use the term malware to describe malicious software.
There are many different kinds of programmed threats. Experts classify threats by the way they behave, how they are triggered, and how they spread. In recent years, occurrences of these programmed threats have been described almost uniformly by the media as computer viruses and (in the more technical media) worms. However, viruses and worms make up only a small fraction of the malicious code that has been devised. Saying that all programmed data loss is caused by viruses is as inaccurate as saying that all human diseases are caused by viruses.
Experts who work in this area have formal definitions of all of these types of software. However, not all the experts agree on common definitions. Thus, we'll consider the following practical definitions of malicious software:
Security tools and toolkits
Usually designed to be used by security professionals to protect their sites, these can also be used by unauthorized individuals to probe for weaknesses. rootkits are a special case: these are prepackaged attack toolkits that also install back doors into your system once they have penetrated superuser account security.
Back doors
Sometimes called trap doors, these allow unauthorized access to your system. Back doors , also called trap doors, are pieces of code written into applications or operating systems to grant programmers access to programs without requiring them to go through the normal methods of access authentication. Back doors and trap doors have been around for many years. They're typically written by application programmers who need a means of debugging or monitoring code that they are developing.
Most back doors are inserted into applications that require lengthy authentication procedures or long setups requiring a user to enter many different values to run the application. When debugging the program, the developer may wish to gain special privileges or avoid all the necessary setup and authentication steps. The programmer also may want to ensure that there is a method of activating the program should something go wrong with the authentication procedure that is being built into the application. The back door is code that either recognizes some special sequence of input, or is triggered by being run from a certain user ID. It then grants special access.
Back doors become threats when they're used by unscrupulous programmers to gain unauthorized access. They are also a problem when the initial application developer forgets to remove a back door after the system has been debugged and some other individual discovers the door's existence.
Logic bombs
Hidden features in programs that go off after certain conditions are met. Logic bombs are programmed threats that lie dormant in commonly used software for an extended period of time until they are triggered, at which point, they perform a function that is not the intended function of the program in which they are contained. Logic bombs usually are embedded in programs by software developers who have legitimate access to the system.
Trojan horses
Programs that appear to have one function but actually perform another function (like the Greek horse that was given to the city of Troy near the end of the Trojan War—a horse that appeared to be an idol, but was actually a troop carrier). Analogous to their namesake, modern-day Trojan horses resemble a program that the user wishes to run—e.g., login, a game, a spreadsheet, or an editor. While the program appears to be doing what the user wants, it actually is doing something else unrelated to its advertised purpose, and without the user's knowledge. For example, the user may think that the program is a game. While it is printing messages about initializing databases and asking questions such as "What do you want to name your player?" and "What level of difficulty do you want to play?", the program may actually be deleting files, reformatting a disk, or posting confidential documents to a web site in Argentina. All the user sees, until it's too late, is the interface of a program that the user is trying to run. Trojan horses are, unfortunately, sometimes used as jokes within some environments. They are often planted as cruel tricks on hacker web sites and circulated among individuals as shared software.
Viruses
A true virus is a sequence of code that is inserted into other executable code so that when the regular program is run, the viral code is also executed. The viral code causes a copy of itself to be inserted in one or more other programs. Viruses are not distinct programs—they cannot run on their own, and some host program, of which they are a part, must be executed to activate them.
Worms.
Worms are Programs that propagate from computer to computer on a network, without necessarily modifying other programs on the target machines. Worms are programs that can run independently and travel from machine to machine across network connections; worms may have portions of themselves running on many different machines. They do not change other programs, although they may carry other code that does (for example, a true virus).

How to Remove Antivirus System Pro
How to Remove Antivirus System Pro
by: James Anderson19
Antivirus System Pro acts like any other malware and scareware bug. It is crafted in a way so that it can scare computer users and force them to buy the complete fake version of this software. Once you buy it will invite more virus to your system.
Here is what it can do to your computer:
1.Show false error reports
2.Performs a false security scan of your PC
3.Download malicious threats onto the computer
4.Floods your desktop with irritating popups
5.Reduce the speed of computer.
6.Tries to scare PC users and force them to buy the complete fake version and scam their money.
7.Keeps track on computer information that includes confidential and personal details such as account numbers, logins, passwords etc.
8.It keeps your online identity at risk.
9.Makes the users to waste more time and money by searching and buying for a good antivirus software that will be able to remove Antivirus System Pro
What it cannot do:
1. It does not protect your computer from infection
2. Does not identify incoming or existing contaminations
3. It is quite expensive
4. Cannot remove viruses
Therefore it is necessary to remove Antivirus System Pro once you get the trace of it in your computer. But the process of removing Antivirus System Pro is not very easy. Only a person who has sufficient knowledge on computer as well as the registry files. But if you are not a very computer savvy and do not have any idea about the process you should not try to do this yourself.
How to delete the infection:
1. You need to check first whether all the symptoms that indicate the infection are present there in your system.
2. Find the list of registry files and execute the process by comparing the list with the list of Task Manager.
3. You can also delete the infection erasers, editors or registry cleaners.
4. Find the related DLL files and delete them.
5. Locate files to remove Antivirus System Pro. You can use Windows search tool and keep the track of folders, path files etc.
6. Restart the computer.
As this nasty software program has the ability to recreate themselves you need to delete all the infected files carefully. Otherwise there may be a chance of further infection if a single file is left undetected and undeleted.

Finding A Personal Solution To Personal Antivirus
Finding A Personal Solution To Personal Antivirus
By Ms Mindy Matter
There are many programs out there today, but a few of them aren’t as worthwhile as they should be. Personal is one of the many concerning programs out there today that advertises itself as the solution to your problem, yet causes more difficulties than it should.
Understanding Personal Antivirus
Most security experts classify Personal as a rogue program. The Zlob Trojan is usually responsible for its installation on your computer. More often than not, the files are disguised as video codecs, and they can be installed on your machine if you click a pop up that asks you to install a program to view part of a web page. Because there are more than thirty-two different variations of this Trojan, it can be tough for security software programs to stay on top of this one.
The program itself was designed by Innovagest 2000. There are two related programs. The rogue program called General and the one called Internet are both clones of this one. All three are designed by the parent company. If Personal does get installed on your computer, you may notice a number of different things.
The most common trait individuals notice with this program is its scanning window. It was created to mimic the Windows Security Center interface, and you may see it on a fairly regular basis. The goal here is to get you to purchase the full version of the program, and in the top left corner, you’ll probably see the Personal Heading with a gold and silver shield, the program’s logo. You should also see a button that says something like “Get full time protection” at the top of the screen. To the left of the application window, you’ll see many different menu buttons including Overview, Virus Scan, Activate Product, and Update Product.
You might also notice the box for statistics. They tell you a bit about the last time it scanned your computer, the last time the program was updated, and a bit of information about the version of the program that is installed on your computer. Much of the rest of this program’s window displays the information about that scan. You might see lots of different file names during the scanning process, and some of them look like convincing infections. Because that scares so many computer users, it is essential to note that these aren’t actually part of your computer. Personal
Antivirus finds the exact same results on every computer it’s installed on, and once you remove this program, you’ll also remove any traces of these file names, leaving you with a bit more peace of mind.
The scanning window, though, isn’t the only part of this program that you might notice. Most users notice a variety of pop up advertisements. Some look like the typical pop up ad you might find while you’re browsing online. Others, though, will resemble the Windows Notification Balloons your computer often uses to tell you about important updates or other essential information. Most of these have a heading like “Trojan Found” or “Security Warning.” No matter which type of pop up you’re experiencing, you’ll be asked to click on the ad itself to either activate your level of protection or update it. Should you choose to click, you will typically find yourself directed to the Personal home page. It not only tells you about the benefits of the program and how much you need it, but it will also ask you to purchase the full version of the software.
During any given browsing session, pop ups aren’t the only thing you may notice. You might also note that your overall browsing experience has changed a bit. Not only does Personal have the ability to change your chosen start page and some of your bookmarks, but it can also redirect you to another page while you’re browsing. Seeing pages that say something like “Security Warning” or “Update your Virus Protection” isn’t uncommon with this program. Clicking on them leads you back to the purchase page for the program.
In addition to these indicators, you may also notice that your computer runs a bit slower than it once did. Personal was created to run as soon as you turn your computer on each day. That means that no matter what kinds of applications you’re running on your computer, Personal is running in the background. As a result, when you try to run a program or switch between different applications, you may notice everything takes several minutes instead of just a few seconds. Moreover, when you’re trying to open a web page or view a video online, Personal may slow that process down too, as it can use up quite a bit of bandwidth.
If you do have Personal installed on your computer, the best idea is to remove it with the help of a respected antispyware solution.

Free Antivirus
Free Antivirus
By imtechfirst.com
We often experience problems with computer virus, nearly all computer users have experienced this, even up to a headache. What a headache? Our important data are duplicated by a virus and lost the original of file.
How to remove a computer virus is actually easy and simple, most simple way is format hardisk that infected virus. There are many ways to delete computer virus than to format hardisk, including the antivirus.
Antivirus software is important to be installed on the computer, especially if you do not want to lose important data. that installed on computer also must always update regularly to prevent the new virus and that variant.
There are many programs are outstanding, of which pay up to a free. Here are some free that I use for a normal install on the computer.
Avira AntiVir Free (www.freeav.com), is a free that quickly identify the new virus and that variant, and then delete them. I think Avira the winner this time with the
ability to quickly identify the virus and the new variant, which is always fertile pop. Avira can update regularly, either online or manually update, if want manually update we can download file update on avira website.
AVG Free Edition (http://free.avg.com), avg does not want to lose with avira, this anti virus also has many advantages, namely the feature LinkScanner, Active Surf-Shield and LinkScanner Search-Shield that will help you when surfing on the internet.
Free Avast Home Edition (http://www.avast.com), is one of the software free to use them as conditional for free (one year) We must apply to get its license key that will be sent via e-mail.
PC Tools (http://www.pctools.com/free-antivirus), is equipped with Smart Update function of the database to retrieve the latest virus from the internet.
Besides the antivirus, many others that you can download and use for free. I mentioned above is just as small and is a widely used anti-virus.

Microsoft "morro" : A Threat To Established Antivirus Vendors
Microsoft "morro" : A Threat To Established Antivirus Vendors
By piru
Microsoft released a limited beta version of Microsoft Security Essentials codenamed Morro on June 23, a free application for users of Windows XP, Vista or 7. It is free software that provides protection against viruses, spyware, rootkits and Trojans. But, it was available for download to the first 75,000 people in the United States, Israel, China and Brazil.
Security Essentials is easy to install and use. It replaces company’s Windows Live OneCare, a subscription service and Windows Defender, which only protects users from adware and spyware. The new product aims to cover the basic security needs of home users and its easy-to-use interface appears to be taking the right approach to the task.
Symantec and McAfee, two major vendors criticized the new software and said it was not comparable with their own offerings. But, AVG Technologies responded positively and said it reinforced the company's ideal of free software.
Minimum system requirements for Microsoft Security Essentials Beta:
1. Operating System: Windows XP; Windows Vista; Windows 7 (Beta or Release Candidate)
• For Windows XP, it requires CPU with clock speed of 500 MHz or higher and 256 MB RAM or higher
• For Windows Vista and Windows 7, it requires CPU with clock speed of 1.0 GHz or higher and 1 GB RAM or higher
2. Internet Browser:
• Windows Internet Explorer 6.0 or later
• Mozilla Firefox 2.0 or later
3. Under any compatible operating system, a VGA screen, 140 MB of free space and an Internet connection are also required.
Development of the MSE
Microsoft had announced Morro on November 18, 2008, but its beta
version was released in June. It is expected that MSE will be finalized and released before the end of calendar 2009. Redmond giant reported that MSE will be launched in 20 markets, available in 10 languages.
MSE Interface
Its interface is clear-cut and cleanly designed. At the top of the window, you will see your computer's protection status that is protected, partially protected or unprotected. Everything else appears in four tabs: Home, which shows you an overview of your settings and has a Scan Now button, Update, where you can manually update your virus-definition files, History, which logs all of the malware cleaned from your system and Settings, which is self-explanatory.
Features
MSE is a stripped-down version of Windows OneCare, solely providing malware detection and removal. Before installation, MSE checks for a validated copy of Windows. No registration or personal information is required. The program will disable Windows Defender automatically, as it provides protection against malware, not limited to spyware and adware.
Updates are published 3 times a day to Microsoft Update. Using default settings, archived files are decompressed and then scanned. File downloads and e-mail attachments are also scanned. Its Dynamic Signature Service attempts to better identify malicious files by checking for updates if an application exhibits suspicious behavior.
Before taking action against a suspect file, MSE prompts for user input. If no response is received in 10 minutes, then the suspected malware is handled according to its default action, letting MSE determine what to do with the malware.
System Restore points are created before removing found malware.

PERFECT STEP CLEANING PROCESS
PERFECT STEP CLEANING PROCESS IS:
If you run your personal computer:
• Boot your computer with startup disc clean from virus (and write protected)
• Run virus scanner/cleaner program to infected file
• Try to open the file, if the file broken, don’t continue.
• If the program run well, try it to some other smaller or bigger file size. Big size files need to be checked, usually they have internal overlay that caused the the file broken if they infected.

THINGS YOU NEED TO DO AS USER
THINGS YOU NEED TO DO AS USER
As an program user, there are few things you need to do to minimize the risk of using antivirus:
• Find a good antivirus, good means that the program is trusted to detect and clean the exist viruses. Don’t take promises form vendors. Try to find comparison from different from articles and internet.
• Always use new antivirus, you can download them from internet or from magazines. Old have big risk if you use them more than 6 month.
• Make backup data and program that you think important for you.
• Do the cleaning process correctly if you found a virus.
• Make sure that your program is original, there are chances for someone to change the antivirus, or infect it with a virus.
• Call the expert if you think you can not handle the virus inside your computer or network.

The Danger Of Antivirus Program
The Danger Of Antivirus Program
By The Gadgets!
Since the first time found, virus has very big evolutions, so is program. Unfortunately, program evolution ussualy only follow the virus evolution too, not ahead of it. Expired (in technology) will be danger for users.
When viruses detected, new viruses will always born with newest technology and make become powerless. Old for example, can be cheat with “stealth” technology, so when try to detect other files, stealth virus will spread themselves to every checked files.
You often read about “specific” programs which mean to detect one kind of virus. Ussualy the programmer did not tell you the right way how to use the program, in fact that specific has a big risk if you don’t use it correctly.
Specific can only detect one kind of virus (and maybe some of the varian) and ussualy paralized the virus in memory. If you found a virus and you know the virus name, you can use this kind of antivirus. But if you are not sure with the name of the virus, you better not try it. And if there are other virus in your computer, which obviously not detected by your antivirus, then this will be a trigger for the other virus and spread them to all scanned files.
The most frighten danger is that if is mistaken to detect a virus and clean it and caused a program you try to fix become broken.
THE DANGER SOURCE OF PROGRAM
Antivirus could be danger because of the following reasons:
• Some programs only use simple technique which will be easily trickked by virus programmer. For example, if program only checked in few byte in header of the virus, virus programmer could make other version of the same virus (varian) with the same header, but different in other important part, like encryption routine/ header description. This will make an a file destroyer, not file saver. Some can also be cheated by change the signature file. Signature file is file that contain ID from every virus known by antivirus, if the Id is changed, then won’t recognise them. Good should always check if the signature file is changed.
• An program doesn’t create backup file cleaned. Mostly an program (specially the specific) don’t provide media to create backup file, eventhough this is very important just in case the scanning process fail.
• An anitvirus program doesn’t do self check. Self check is necessary, an program could be change by other people (beside the programmer) before it come to the user. Commercial programs ussualy doing self check to make sure they are not changed by anyone, but some don’t do this, and this is danger. On local programs, which usually included by some computer article, include the source code, you better compile the source your self if you hesitate to the original file exe.
• program residen can be non activated easily. Good residen should be undetected and uninstall easily. Bad residen sample is VSAFE (in DOS package). VSAFE is detectable and turn off from interrupt (try to learn/debug VSAFE program in DOS). Users will get the fake safe feeling by using this kind of antivirus. Better not safe at all than fake safe.
• program don’t warn for expired date. By the time, new viruses will come with their newest technique. A good will warn you if they are out of date. This is necessary to avoid the “antivirus spreading virus” case.
By The Gadgets!
Since the first time found, virus has very big evolutions, so is program. Unfortunately, program evolution ussualy only follow the virus evolution too, not ahead of it. Expired (in technology) will be danger for users.
When viruses detected, new viruses will always born with newest technology and make become powerless. Old for example, can be cheat with “stealth” technology, so when try to detect other files, stealth virus will spread themselves to every checked files.
You often read about “specific” programs which mean to detect one kind of virus. Ussualy the programmer did not tell you the right way how to use the program, in fact that specific has a big risk if you don’t use it correctly.
Specific can only detect one kind of virus (and maybe some of the varian) and ussualy paralized the virus in memory. If you found a virus and you know the virus name, you can use this kind of antivirus. But if you are not sure with the name of the virus, you better not try it. And if there are other virus in your computer, which obviously not detected by your antivirus, then this will be a trigger for the other virus and spread them to all scanned files.
The most frighten danger is that if is mistaken to detect a virus and clean it and caused a program you try to fix become broken.
THE DANGER SOURCE OF PROGRAM
Antivirus could be danger because of the following reasons:
• Some programs only use simple technique which will be easily trickked by virus programmer. For example, if program only checked in few byte in header of the virus, virus programmer could make other version of the same virus (varian) with the same header, but different in other important part, like encryption routine/ header description.

Specially designed softwares affect stability of the systems, and these software programmes may be malwares. Antivirusprograms consist of computer programs that aim to identify and reduce computer viruses and other harmful softwares or malwares. An infected system or machine shows certain suspicious behaviors, which seems irregular or abnormal. Several antivirusprograms and anti-malware programs can be of great use for preventing the required attempts of these viruses to affect the nature of the system. If one program attempts to write data on an executable program, the antivirusprograms can determine this suspicious behavior, alert a user and ask for further directions. Anti-malwares are exceedingly essential as nowadays with the technological advancement it is necessary to communicate electronically.
For personal computer users it is essential to prevent the viruses. Anti viruses are essential as these are designed to keep personal computer users aware about the latest signatures within the anti-malware industry. Anti–malwares cautiously examines the files and scans and checks if any viruses are found. The deletions of the found viruses are possible using the anti-malwares. Antivirusprograms are extensively used for better maintenance of systems. With the spread of viruses using electronic mail, their infection vector could be spread far more inexpensively and effectively. Without the need to install additional antivirus software, the attachment can be well scanned before downloading.
Besides installing the anti-malware, user education is extremely important. As malware is specific software, designed to damage a computer system without the owner’s consent, it has been named after blending the words “malicious” and “software”. Many ordinary computer users are till date not aware about the antivirusprograms. Basically, the expression is a mixed term used by the computer professionals. Moreover, it is worth mentioning that the normal computer users should be well aware about the viruses, which immensely affects the computers. The term malware has been newly coined.
In the past few years, the fact has been revealed that the main intention of creating the malware is for enhancing financial frauds. This has been a major cause behind the popularity of anti-malware. As most computers consist of bugs, malware can effectively track them. So, it is indeed essential to effectively track the self-replicating viruses using the anti–malware. Antivirusprograms help in maintenance of the system’s security and moreover it protects against the malwares.
It is most crucial to note that malware is a broader category of virus, which can be highly detrimental for a computer system. Some viruses are programmed to spoil the computer by damaging programs, deleting files, or even reformatting the hard disk. Others are not designed to do any damage, but purely to replicate themselves and make their presence known by presenting text, video, audio messages etc. To prevent data loss and system crashes antivirusprograms are of high importance. Computer viruses can be also spreaded through messaging. To ensure that the computer is protected from malwares, a working antivirus program is highly necessary.

Why Use Antivirus Software?
Why Use Antivirus Software?
by: Eric Koshinsky
This is a really simple question to answer – you need to use antivirus software to protect your own computer, and to prevent your computer from being used to pass on infections to other machines without your knowledge. If you use the internet and you don’t take precautions, you’re going to get infected. And you’ll infect others, including those you care about most like your friends, family, and business contacts because their information is in your email address book and other files on your computer.
If you don’t care about infecting others, let’s look at the economic argument for a moment. You have a computer that must have cost at least $600, and perhaps as much as $4,000. On top of that you’ll have a monitor for which you paid between $250 and $1000, and you’re running software costing at least $500 dollars. If you have business or specialist packages installed then I’m guessing you may have invested $5000 in software alone. You will probably pay upwards of 25 dollars a month for your internet connection. And if you store personal data on your PC, it is probably worth more than money to you.
So you’ve got equipment worth something like $1400 if you’re computing on the cheap, right up to (and beyond) $10,000 if you flex your wallet a little. Think of this as being the same in price as an acceptable older used car right up to the pretty good used car you could buy for ten thousand dollars.
Now imagine that the car had all the locks removed and could be started without a key – and of course you could paint “STEAL ME” on it for good measure. That makes a lot of sense..yea right!
Having a computer that does not have up-to-date antivirus and firewall protection is pretty much exactly the same. You are simply asking for trouble!
This kind of trouble doesn’t need to be invited twice, because viruses, worms, Trojans and all the rest, are designed to find unprotected computers and attack them. They don’t seek out protected computers! If they find one, they simply move on.
NOTE: Firewalls are one good way to keep the net-nasties moving on, you can learn more about them at: http://www.antivirus-report.com/freeware-firewall.html
Remember, computer viruses are designed, they don’t just happen by accident. Because human intelligence is behind the viruses they develop quickly, use surprising and unexpected tactics, and they hit us where we are weakest.
So if you can afford over $1500 on a computer and $300 a year on internet connections, you can definitely afford another $50 to make your computer safe (and prevent it from being used to spread viruses and Trojan horses behind your back).
If you’re not convinced about the cost argument, consider the case of David L. Smith - the self-confessed author of the infamous Melissa worm. When he was sentenced to 20 months imprisonment and a fine of $5,000 in New Jersey, the court adjudged Smith's worm to have caused more than £55 million pounds worth of damage!
Against the cost we stand to lose, the risk of losing our priceless personal files, and being blamed by friends and relatives for infecting their machines, the top antivirus software programs cost as little as 2 months internet connection. They all include constant and unlimited automatic updates that keep your system safe and clean.
And if you weren’t convinced by the good citizen argument that you should protect your computer to stop others getting infected, then it might be worth mentioning that there is a movement to make people not using antivirus software legally responsible should their machine be used as part of an attack (even if they did not know about it). (Note: I’m not personally a part of such a movement, but it does have its merits!)
So, be a good citizen whilst protecting your wallet and your sanity by installing good antivirus software and keeping it up to date.
