The Blaster virus has played havoc with many of the computers where I work. Since the antivirus software didn't know about it, it hit a lot of us. My lappie got snaffled, but neither of my desktop machines got hit. I ran the patch program on everything as soon as it became available, but for some reason it didn't always "take" on laptops. I ran it a second time and it fixed the problem.

There is no hell too hot or too deep for virus creators.
