It sounds like a hijack. This is one of the main reasons I hate Windows, because you can just be browsing along and going to some website and bam, you're infected... Without any knowledge whatsoever that something is being downloaded AND executed to your computer.
This is the main reason I went to Mac. Sure, Mac *can* have viruses, but the chances of you being infected to the point where your system requires 3rd party software to "fix it" is very slim to none. That's all based on how the OS was designed in the first place. Like anything, if you give a software permission to run as root, yes, it can attack your kerenl and system files. But with Windows, it permission is irrelevant, it just allows it
DWB, you may be able to just check your hosts file under system32 and remove any entires the virus might have put in place. That might get you back up and running.
Good luck man
