Antivirus 2009 (or 2008, or Antivirus XP2009 or other names - there are many clones of this rogue software) is a piece of malware that infects your computer and constantly pops up notices that you have an infection and you have to buy or update Antivirus 2009. This is a scam to trick you into paying $30 for some useless software. The malware installed when you downloaded something from the web, sometimes masquerading as a video codec or other useful software. It is persistent, and infects a number of Windows files.

OMG, I had the exact same problem, trust my advice, go to the help page and look up system restore. Follow the wizard that takes you through it and it will shift your computer back until the day that you choose. This worked for me a few times with viruses. Whatever you do don't click anything on the Antivirus stuff. Its actually a really bad virus that tricks you into clicking it.

If your browser is misbehaving (POP-UP's, going to weird, unrequested sites, goofy warnings, etc.) do this BEFORE other major system makeovers:

Apart from removing any malware already installed on your system, you must

TURN OFF 3rd PARTY COOKIES!!

This stops un-requested cookies ( =pop-ups & websites) from being displayed in your browser.

For Internet Explorer: go to Tools> Internet Options> Privacy> Advanced: here check 'Override automatic....' 'Allow session cookies' 'Allow 1st party cookies' & 'Block 3rd Party Cookies'.

For Firefox: go to Tools> Options> Privacy: here un-check 'Accept 3rd Party cookies'

Junk in your system will have to be extracted with Spybot, Ad Aware, and all available good cleaners. Good luck.

Your computer is infected with rogue software. Download and run rogue antispyware removal tool from http://www.spywaregeeks.com/ to remove the rogue software from the computer.
