Popular site like Facebook, Myspace and any other soucial sites may be a hot spot for banners with virus replated installs. Some antivirus programs have found popups that link to other malicios sites and stop the acces but some slip thru the cracks. Try to keep your software up to date everyday.
Disconnect the computer from the internet to avoid other uploads from the virus. Turn your system off and start it back up but on safe mode by hitting the F5 button or F8. Then try to remove any files or executables from the startup folder located in the START/ALLPROGRAMS/STARTUP.
Anything in this folder can be removed without it creating errors to your system. Finally if you are brave enough to go to the registry you can also try removing anything that looks suspisush on the run Key located in the
HKEY_LOCAL_MACHINE/SOFTWARE/MICROSOFT/
WINDOWS/CURRENTVERSION/RUN
There is no perfect Antivirus software but it is your preference on what you like:
DVD Backups and system check points.
