You need a virus?
Hey our computer can muck it's hard drive to hell without a virus.. we have windows me. Installed over windows 95. When we had a blue screen (frequent with ME) it went over to automatically defrag, how helpful, but some of the old registry files were still lurking. So which did the defrag choose to use? The old ones of course. Took many days to get it back up and we lost most of the files. So watch out for disks with little red, green, blue and yellow windows on them or an e-mail with "Try our free Microsoft introductory offer", even NOrton won't stop those...
