run hijack this and post the logfile it creates, I can check that for Trojans for you

This is the information that AVG believe relates to you

Personally speaking I consider AVG to be not worth paying for which is why its free, it identifys so much that no other application identifys yet they provide minimal information on many of these files and less information regarding resolving the issues... false identification perhaps.

I would also suggest either double checking with the online scanner housecall by trend micro or download a trial of NOD32
