The kind folks over at AVG have put together a document to help those whos computers may be infected with irritating virii and spyware.
Cleaning an infected computer today has become harder than ever. To effectively clean your system you must first learn a little about what you are trying to get rid of and what tools you need to get the job done. I’m going to try to give you some of the background, followed by the basics of getting rid of these pests.
They go on to say:
Today there are a variety of things that can infect your computer such as viruses, worms, trojans and spyware. I refer to all of them as malware since that word seems to best describe them and covers both viral and spyware related issues. I find it best to use a multi-pronged approach to fighting malware, so I use several software programs to find and get rid of them. Hopefully, by giving you a little of the background, you will be able to learn what tools to use and when to use them so that you may clean your computer of the malware you may encounter.
Viruses were the first computer bugs, and anti-virus (AV) software was made specifically to detect and get rid of these. Worms are a little different than viruses, which is one reason why AV software has had a harder time catching them. Next came trojan horses, usually just called trojans. These are very different than both viruses and worms. They actually take advantage of the weaknesses that are inherent in AV software. For one, most trojans actually try to hide from being detected by AV software. They also work “smarter” by creating hidden copies of themselves so that when they do get detected and cleaned, they can re-infect the computer with the hidden copy right after the AV software cleans the original infection. Basically, trojans are AV software’s worst nightmare simply because AV software wasn’t designed to specifically go after this type of threat. Today, AV software is much better at detecting all types of malware. With the release of AVG 8.x.xxx… it now combines both an antivirus with an antispyware scan to help users fight both viral and spyware related issues.
Spyware isn’t a new bread of malware. It is simply a combination of various computer exploits and they utilize various combinations of scripts, trojans and worms. Currently they take advantage of trojans the most since they are harder to detect and clean properly. Anti-spyware (AS) software was created specifically for detecting and cleaning this type of malware, so when it comes to trojans and some worms, AS or a combined AV/AS software is much better equipped to fight these than the AV only types of software such as the earlier versions of AVG.
A new varient of spyware is the Rogue type of malware software. This type of software pretends to be useful utils like antispyware, antivirus, hard drive and/or registry cleaning utilities but really their only goal is to sell you their useless software or to install other spyware onto your system. They do this by falsely stating you are infected by something or have other issues that could affect the performance of your system. They usually are installed using the “drive by installation” method that happens when you may visit various malicious websites, often installing without your knowledge.
There is also another type of detection that AVG and most good AS softwares will detect and they are only detected because of their potential security risk if a user was unaware of their existance. AVG calls this type of software Potentially Unwanted Programs ( PUPs )… others may refer to them as hacktools, riskware, or simply “not-a-virus”. These are normally very useful utilities.. but since they can also be used for harm, AVG and other utils will detect them so the user is aware of their existance. Examples of these are utilities to recover forgotten passwords, forgotten software keys ( like the Windows install key ), IP scanners, remote control software and a variety of similar utils. If you have any of these installed or on your system, you will want to exclude them from detection with whichever utility you are scanning for malware with… or at the very least do not have them removed when you are cleaning the system up. Remember that these are not malware and do not do damage to your system BUT if you are unaware of their existance, it could be a sign that a hacker may have placed them on your system to do harm. A quick rule of thumb, if you are aware of their existance leave them on your system… if not quarantine them and check out what they really are later.
I suppose I should also cover one last subject before moving on to the cleanup steps… Tracking Cookies. AVG as well as most antispyware utils do detect these and each has a specific but different list of the ones they will find. These ARE NOT MALWARE.. they can do no harm or damage to your system. They do however represent a potential invasion of your privacy since they can be used to track your internet browsing habits. So unless you have setup your browser to block them or use a specialized utility to do that… you will always find these detected. So do not be alarmed by their presence.. clear them if you want ( I always clear mine )… but also understand that they will likely return the next time you happen to visit a website that may use them.
First, you will need to get some software programs to help you. The following programs are what I use personally. Not only do I trust them, but they are also free for personal use. The companies that provide the free software, also provide software that they sell for use in a commercial environment. Usually, the free versions are just as good but simply don’t have as many of the extra features which make the commercial versions even more attractive to use.
They then detail the tools you will require to clean up your computer so head on over there for more information and good luck in getting rid of your problems!
