which virus (comp) you hate the most??

Slow-developing worms. They can enter a system and won't affect anything for weeks, even months. Then they hatch and wreak havoc. After bring burned a couple times -- even with the Norton Antivirus installed -- I went in another direction and it has been, to this point, extremely successful. I installed a free version of AVG off its web site, and it was so effective that I went on and have paid for two years' automatic protection after the four-month trial wiped out my present viruses and is annihilating anything else that gets in. It's been terrific, and it has to be because I am now on AT&T's broadband service (which is quite good, by the way) is pretty much on 24/7 and picking off these various viruses and worms and nipping this problem in the bud is something I would recommend to anyone.
