Thought I posted to here, but it must have gone Twilight Zone on me.
Anyhoo
After you've got everything back to normal and it's all bright and shiny again, get yourself a drive imaging program. I prefer DriveImage, but Ghost will work as well (I believe so, anyway, with what I'm about to say).
Install DriveImage, create the rescue diskettes they want you to make, and then image your drive, making them CD sized if necessary. Back up your drive this way so you can always go back to that point.
In my own use, virus programs slow my systems unacceptably, don't guarantee me protection from the newest viruses (in which case, I've paid for a program that is always "catching up"), and depending on the program, don't always catch even existing viruses. They also cause wonky behavior with other programs, requiring me to go to lengths to make nice with the other progs.
I've imaged my drives and backed them up to another partition/drive and if it's a VITAL system, to removable media (CD).
I've been hit by 2 viruses, numerous spamware/spyware/adware. Each and every problem/nuisance is at most a 10 minute fix away from being back in the pristine state I chose to image.
Virus scanners suck.
(did I forget to mention the "pay for updates" annoyance that drive imaging doesn't require?)
That's my $.02 on what to do AFTER you are back to a state you like, and my advice for future PC setups.
