Download.trojan HELP!!!!

[sweet angel]

When I got home tonight and turned on my PC, I got a virus message. I run Norton Antivirus and update my virus definitions regularly, as well as always having "live update" enabled.

This was not a normal "this email is infected" yellow warning. This was a red warning box. The path was: c:\documents and settings\sue\local settings\temp\susp.exe

It was unable to quarantine or delete the file.

I went to Symantec's page and their suggestion was to turn off System Restore, update virus, restart in Safe Mode and run a full system scan, then delete any infected files.

When I did all that, no infected files were found, when previously there were three (two of which I was able to delete and one of which I was not able to delete or quarantine).

My question is this...how can I be sure that I'm no longer infected? I ran the virus scan AND searched the computer for the susp.exe file. Both came up blank. I just have this nagging suspicion that it's still infected.

Any clues for me?

First person who suggests that it's a scuzzi problem incurs the wrath.....

Thanks in advance!

**EDIT: damn it damn it damn it! I just ran Virus Scan again and it's still coming up with one file that it cannot quarantine and cannot delete!

HELP!!!!!!!!!!!
