the avg suggestion is good - but what you are describing is "adware"

there probably isnt a virus, its just an advert trying to get you to buy antivirus software.

what you need is a piece of software that will remove the pop up.

google for "ADAWARE"

Install and run that - also make sure you have antivirus software installed and running at all times.

Good luck
