Don't worry about running TDS-3 with Norton as this is not a program that will monitor your computer live. It will just do the scan and that's it.
Norton? I have nothing good to say about that program.
Most of us here would agree that Norton is a huge resource hog and sometimes cause more problems than it's worth. We recommend using
Grisoft AVG instead. Not only is it free (for personal use), it does a much better job than Norton.
Yes, we will need that TDS-3 log just to see if there are any trojans - and remove them if they exist.
