lol mcafee
i had that a few years ago, it was complete stuff.
it could easily find the viruses, but the program was so loving stuffty that for half the viruses it couldn't delete them. yup, that's right, an anti-virus program that can't even get rid of the viruses it finds. i would have to go manually searching around the computer's files for the corrupted files (which were usually buried in 30 folders) to delete them. mcafee would start to download updates whenever the forget it felt like, and it would window anything running fullscreen to helpfully tell you that it has downloaded an update and you should probably restart the computer, like now.
