Since I released this tool back in 06 118 people have downloaded it to remove this nasty virus. Once you get it it erases all your music files and then prevents you from booting your system.
Download this program w32.nopir.c-p2p-worm-fix-v2.zip On another computer. Copy it to your computer. Likely will have to use a cd or a disk. Reboot your computer following docs and run the script. It will remove the hack files and the hooks that load them. You should then be able to reboot to windows. This was writen for XP it is unknown how the virus will work on Vista.
