Unknown sneaky keylogger (HELP!)

Hi, ive come across a very very sneaky keylogger. Its logging every site I visit in IE to C:\Documents and Settings\Anthony\Local Settings\Temp\$.ficn$

Ive noticed other people with it, this guy got his solved, or at least he thinks he does. http://forums.majorgeeks.com/showthread.php?t=152593&highlight=at+wit's+end

Ive opened Process Explorer and noticed the following habits. Nothing happens until i run IE, but when i do, another process called IE is created as a child of that. Then soon after, Kaspersky notices it trying to call "iexplore -tt 2068", the parameter -tt is always the same and the number is always the PID of the IE process. This happens every 10-20 seconds from then on.

Kaspersky also notes that its making loads of registry entries, ive checked these out and it seems like its trying to propogate via USB drives, its changing loads of autorun parts.

SuperAntispyware found a few malwares but their all old things from previous XP backups, ive never even gone into them since, this is a 2 month old XP install with SP3.

Ive followed the FAQ's, I still have this keylogger. Searches dont turn up anything. Please help!

 

Thanks very much for trying to help, but ive solved the problem. Its a long story but ive been chasing a malware that never existed. The logs that were being made were part of an addon i was using (and have been for a long time), a recent undocumented version update was logging certain details of websites to C:\Documents and Settings\Anthony\Local Settings\Temp\$.ficn$

And on a side note:

These are not cracks. And this is my personal computer.

Sorry to have botherd you, I value the time youve spent trying to help me. Thanks.
