not come across the virus but things to try and kill it.
Search registry and find the key that runs it when your PC is first swiched on and delete it.
next delete the running file with software like
http://lockhunter.com/ or FileASSASSIN.
If above doesn't work use Explorer or My Computer to find the location of 'temp.exe' then Reboot and F8 and boot to C:> prompt then CD to the required directory and delete manually before Rebooting to windows to test.
Other tip...
Use a Firewall to stop files like this connecting to the web, which should show what the software is and the location it is on your PC. (ZoneAlarms is good for this)
