Ok, I am scanning my PC now with a anti-virus program called a-squared Free 2.1 and it is picking up some files called:

Trace.Directory.LimeWire 4.12 - 1 traces - medium risk

Trace.File.Limewire 4.12 -20 traces - medium risk
(both of these were detected in limewire)

Ok so what I want to know, (as well as my problem above), is what are these? should I delete them? I may have previously deleted them, is this an issue? Thanks for the help.
