Compare Antiviruses
Anti-virus applications maintain a database of known viruses and compare scanned files that match the characteristics of known viruses. If a scanned files matches those characteristics of known viruses. If a scanned file matches those characteristics, it is quarantined (which means moved to a new, presumably safe location on disk and renamed, so you can find it should you ever need it) so that it cannot affect other files on your system

Some aggressive viruses—such as the Melissa virus—automatically duplicate copies of itself to the first 50 people in your computer email address book. A frightening prospect— opening an email from someone you trust to be greeted by a virus, and that’s exactly what the author is counting on, your trust. The damage caused by these viruses varies from minor delays in computer function to complete destruction of your hard drive. For companies, the price is far higher. A downed website can cost a company millions of dollars a day.
Clean your computer with anti-virus software. If your computer is still not functioning and you have data you are concerned about recovering, consider hiring a trusted expert. Often data can be successfully extracted from an injured hard drive, but the process is complex and will involve another computer, special software, and a technician with a lot of experience in data recovery.
