unfucking a computer, or ask lazy infected lj

[rmd]

So, I have a family member who got what's either a valid antivirus warning or a fake antivirus warning. I suggested shutting down the computer until I can get over there to deal with it.

What's the current set of good solutions for unfucking a computer? I'd like to be able to go over there with a usb drive full of antivirus/antispyware programs in case I need them.

ETA: It's a windows box. I forget what version. Vista, maybe? Might still be XP.

AIUI the only thing you can really do with a pwn3d Windows box is scorched-earth policy: nuke to bare metal and reinstall. Many people actually opt for *replacing the whole computer* rather than attempting to un-virus it.

Sorry if that's less than helpful.
