You may think I am having you redo certain things, the problem is you have not told me for sure earlier if you followed a specific step. When given steps you are not following them in the order given. There are reasons for doing these items in certain order.
Download, install and update this 30 day free trial of Trojan Hunter
Do NOT run it yet.

Update your Nortons. Do NOT run it yet.

Update the AVG anti-spy program. Do NOT run it yet.

Now when you ran this latest HJT scan you had entirely TOO many processes running in the background, many I had not seen before in your other logs;
Limewire for instance. Turn this off and don't run it whle running HJT or cleaning the computer. Which also could be where some of your problems have arisen from...P2P sharing can bring in a lot of nasty items.
Firefox. This is your browser of course but the first rule when running HJT is close all browsers.
RealOnePlayer Updater...totally unnecessary and can be run manually.
Alcohol Soft
uTorrent
Digidesign
Windows Messenger
MAFWTaskbarApplication
Gear CD Burning Software

Turn off all of the above when you run your next HJT scan.

Now Reboot to SAFE MODE.
First run your Norton program, full system scan. Have it FIX whatever is found.
Next run the Trojan Hunter program. Have it fix whatever is found.
Next run the AVG program. Have it fix whatever is found.

Reboot the computer to NORMAL MODE. Make ABSOLUTELY CERTAIN that all of the noted programs above are TURNED OFF and run a new HJT scan. Save the log and post it here along with the latest AVG log.
