How do I get rid of the Facebook virus from my computer?

Use ALL of these programs, as it sounds like you have a malware/adware/spyware issue:

Spybot Search and Destroy

CCleaner

Spyware Terminator

http://www.spywareterminator.com/

Malwarebytes

Unlike anti-virus software, it usually takes multiple anti-malware/spyware/adware to resolve some issues.

If you do not already have an anti-virus installed, I would suggest AVG
