Ok .. its 4:22 AM .. n i've juz managed to remove this Friggin pain in da a$$ .. believe me .. it makes ur life miserable ..
Name - RDRIV.SYS
TYPE - TROJAN
Risk - HIGH!!
Resides in da directory C:\windows\system32
Even Norton Antivirus(wid latest definition) couldn't repair(though it detected).. nor spyware/adware repairs it (i tried many)
This trojan looks naive but doesn't leave .. n sits there warming its seat degrading da system performance ..
Simplest solutions are always da best ones ..
1. Disable da system restore function .. (since many viruses,trojans get back if its enabled)
2. Start da comp in safe mode ..
3. go to C:\windows\system32 folder .. n delete rdriv.sys .. (Simple? .. wait .. it comes back if restarted in normal mode)
4. Go to command prompt and type "EDIT" .. n make a new file wid no contents and save it as rdriv.sys (yeah da same name as da trojan's)
5. wherever u've saved this rdriv.sys(made by u!) move it to da folder C:\windows\system32 ..
6. right click on this file, go to properties and make it read only !!!! (important!!! bcoz since this file is read only .. da trojan in its re-entry fails to take da same filename n is denied its existence )
7. Restart normally .. da trojan should be gone ..

Hope this helps u in da comin times .. incase u get infected by it
