Given a plethora of viruses out in the wild, new malware and variants of existing viruses being constantly discovered a computer can become infected despite all the efforts, as, for instance, in the case of a 0-day attack, particularly if the virus self-propagates, that is a worm. Along the same lines, as makers of malicious software invent new attack vectors, such as relatively new drive-by infection - landing on an infested web page resulting in virus infection without the user clicking or taking any other action – a system’s AV defense may neither be adequate nor sufficient in preventing a computer virus infection.
Fact is that there are countless (tr)additional ways a virus infection can take place, for instance, due to outdated databases of anti-virus software, unaware users of Microsoft Windows installing software from untrustworthy sources, or by opening infected email attachments. The bottom line is that any signs, evidence or manifestation of a computer virus infection demand appropriate action, such as, deleting the virus and running a full system scan clean-up with antivirus software for example.
However, some specific viruses and some types of viruses (e.g. armored virus) can be very difficult to remove by standard means. In addition to that can a virus’ payload damage or undermine system stability, computer security and anti-virus software functionality so that it might be best considering the use of a virus removal tool. Cases when virus removal tools came in handy include dealing with acute virus threats and infections for which vendors of anti-virus software had not yet released a solution, using it as a patch, or, alternatively, fighting acute worm infections of epidemic scale, especially in a networked environment, and doing initial damage contamination just to name a few. Yet, to make use of virus/worm removal tools in general you have to know detail information of the virus or who caused the infection in general.

The Bottom Line
Virus software removal tools can come in handy as complements of anti-virus software, and at the time of this writing I would try Microsoft Malicious Software Removal Tool in combination with McAfee Avert Stinger should there be a need to turn to virus software removal tools but, of course, it is always worth checking all Top 10 Free Virus Removal Tools vendors for a more straight-forward solution.
Note that while these tools will remove viruses and malware, they will not stop your computer from becoming infected in the first place (and prevention is, of course, better than cure!). So, if you are not already running a real-time antivirus solution, be sure to check out Bright Hub's article Top Antivirus Software for Windows 7 (and previous editions) covering for instance, the free top-rated Comodo Internet Security.
