1) If you are on a network with other PCs, disconnect from the network and clean each PC before re-attaching back to the network. The virus spreads through network shares with other PCs.
2) Follow the instructions in the following link at the end of this post as I have performed this w/o any problems.
3) Make sure you hand check the win.ini and registry for the following:
* Run regedit and check for:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
"ScrSvr" = %WinDir%\ScrSvr.exe
* Check the win.ini for the following and remove:
Run= 'C:\WINDOWS\SCRSVR.EXE'
4) Make sure the scrsvr.exe file has been removed from your system

Check out the following link for virus info and be sure to apply the Microsoft patch for your Windows system:
