You do not want to remove the virus(es) immediately since some viruses may infect files that your system requires to run. If these files cannot be cleaned by the anti-virus program, they may be deleted or quaranteened. If this happens you may not be able to run your system again.
d. Scan for viruses but do not remove them. Note: Some viruses will stop your virus scanner from operating. If this is the case you will probably need the help of a computer professional. If you have a virus that stops your virus scanner then you will need to either share the drive across a network and scan it from another computer or remove your hard drive and place it into another computer as a second hard drive, then scan your hard drive.
3. Learn about the viruses you have and how to remove them. - Go to the web site of the organization that created your anti-virus software. The Symantec security response site is a good site to find information about specific viruses and they provide virus removal tools.
4. Remove the viruses.
a. Many viruses have a removal tool which can be used to remove the virus. If there is a removal tool, download it and use it to remove the virus.
b. If there is no removal tool, you will need to follow the manual removal instructions. You may need to manually delete virus files and edit your system registry. The removal instructions will tell you how to do this, but some people may not feel comfortable doing this without the help of a computer professional.
c. If the manual instructions indicate that you should let your virus scanner remove the virus, then remove all viruses that you can with virus removal tools then run the virus scanner with it configured to remove all viruses.
