I had the worm too. It was preventing me from accessing the MS update site, so I copied all important files to my 2nd partition, then re-ghosted windoze from my laptop's install CDs.
Set mt ISP back up and guess what..? As soon as I went Online it started all over again. Either it had infected something on my D: drive or the worm was being puched onto my PC from the internet as soon as I looged on.
Anyway, used the shutdown -a command to keep my pc awake long enough to download zonealarm, then cut the sucker off. Then I ran the symantec gizmo and am now in the painful process of re-installing all the XP security patches over 56k
The moral of the story? Never play poker with a man whose first name is a city.
