I found the virus is in C:\Windows\System32\880uicbv5L.DLL. Re-booted in Safe Mode, but cannot remove with Windows Explorer; get this message: "Cannot delete 880uicbv5L.DLL. Access is denied. Make sure the disk is not full or write protected and that the file is not currently in use."

Also downloaded Grisoft AVG which finds the same virus but cannot remove or quarrantine it either.

What's next anyone?
