Antivir 2009 pop-ups ruining computer?

This stupid Antivir 2009 crap. My cousin Downloaded tghis free AntiVir scanner and it worked fine until last week… I’ve had it for a few weeks maybe a month or two. Now this update has occured. Antiv 2009. it wanted me to install it and it got insane. The pop-ups kept coming. Then this blue thing popped up and my entire pc messed up. It was in big letters and was telling me to do it. Then it said “Beginnign dump of physical memory” or something of that sort. and “Physical memory deleted” it happens every 5 minutes and it gets annoying. It did it again. It says something about spyware.Monster.Fx_ and then some other things i can’t remember. so i uninstalled the AntiVir but the pop-ups are still coming@ help!

The suggestion above is good all thou it doesn’t always work, 2 other programs that could remove it for you are Superantispyware and Malwarebytes.
