Here is a good removal tool

For those who caught the virus and can not get the PC to stay up long enough to download the patch do this.
Open a command line window. Don't know how? Go to start, run and type in "cmd"
When you get the shutdown warning type in "shutdown -a" this will abort the shutdown and give you time to download the patch and fix files. This will need to be done each time you restart until you fix it.
The cause of the reboot is indirectly the virus, the real cause is that on Win XP the RPC is needed to run so many things, the default setting is to reboot when this crashes. And the virus causes the RPC to lose control of it self and eventually crashes.
