I had a computer expert work about 5 hours yesterday on 3 of my computers which had picked up the latest virus. It comes from visiting a URL on the web, not from e-mail. Since I am on a wireless router with my computers, it spread itself to all computers including the lap top. I had a 2000 version of Norton Anti Virus software and it did not catch the virus although it had the latest updates. I had bought the 2002 version but had not installed it. The virus was able to overcome the old Norton software and every time you tried to bring it up it would just disappear. One computer had 11 different locations where the virus had attack, the second computer had 7 affected areas and the lap top had 4 sections that was affected. The 2002 version was able to sort out all this but it took a long time and in one case on the second scan found additional virus locations. This is a very sophisticated virus, not much you can do except keep current virus software. Don
