Security Alert: NetWorm-i.Virus@fp

I keep getting an icon in my toolbar that says:

Security Alert: NetWorm-i.Virus@fp
Type: Virus/Network Worm
Damage Level: High
Description: Virus that infects executable files.
Recommendation: Delete/quarantine immediately
Protection: Click this baloon to download certified Antivirus Software

This in not the only message i get from this balloon and they keep coming up every 2 minutes.
If I click on the balloons it tries to install bestseller antivirus. How can I get rid of this thing. I read somewhere that this may be a part of a program called Security toolbar 7.1 which is also on my computer and I think is causing many pop ups from IE saying that I have viruses. I cant get rid of this thing either. Can someone help me get rid of these things?:cry Help would be appreciated.

 

Ive got a problem. When in safe mode the explorer always shuts down and starts back up again. This causes the computer to slow down and the message which asks if I want to system restore to keep coming back up. Also I have a program called SmitFraudFix. This seems to remove the problem but then after a reboot the problem comeback.
