The Virusburst infiltrates by way of a thing called Icodecpack which you would agree to download when you wanted to look at a porno video. I found a malware protection site called Prevx.com that has a free trial download. It seems to work on keeping those demented warnings from this Virusburst from popping up from your tray. I tried to remove Icodecpack 7.0 from the Add/Remove Programs in the Control Panel. The Prevx software popped up and said I maybe shouldn't do it. I suppose the Icodecpack thing can re-infest itself when you try and uninstall it.

What to do?

See if this self-help guide works:
How To Remove Virusburst (removal Instructions)

Actually I followed those instructions and it appeared that the Virusburst was gone. But when I rebooted, the Virusburst bubbles kept coming back. It seems that Icodecpack somehow reinstalls Virusburst. Problem is, when you try to uninstall Icodecpack from Control Panel-Add/Remove Programs, a window pops up that says "You should reboot your computer prior to uninstalling this software. Reboot now?"
Well that means your screwed. It won't uninstall that way. This evens happens in Safe Mode.

I suggest you post a HijackThis log for examination.
