virus alert

I've been putting off upgrading my AVG for, like, a month now.. and my laptop, once again, is contaminated with a reckless virus/trojan (ack!).

I dont know what to do with this now anymore.

Should I reformat the laptop for the nth time? I mean, I have a new external harddrive now. Should I back up files and all the shit that goes with it?

Sad part is, tha virus attaches and multiplies everywhere. It's very likely that the backup will be saving the virus too.

Sigh. All my external memories are contaminated.

I'm almost desperate.
