trojan troubles

Have a trojan virus. My anti-virus keeps detecting, but can't seem to delete it. Shows as WINNT/system32/oppolo.dll. Now, I can't even boot up (except for safe mode); just gets to the "Windows is starting up" and turns off and reboots. Kept trying to run a Hijack This log, but it keeps generating errors and shutting down, even in safe mode. Did manage to save this somehow:
Logfile of HijackThis v1.99.1
