Your computer is riddled with malware. it will take quite a bit of fixing.
Firstly, make sure you have only ONE antivirus program running at any one time. Your machine seems to have both Norton and AVG on it. If one/either needs disabling please do so.
Secondly firewalls. Again make sure you have ONE firewall running and also make make sure it's a good one, i.e. do not rely on the Windows firewall.
Thirdly, you use Limewire and you visit the FunWebProducts website. Both these will result in your machine being infected with malware. I urge you not to use either.

Next download Combofix from here .....
http://download.bleepingcomputer.com...a/ComboFix.exe
Double click combofix.exe & follow the prompts.
Note >> Do not mouseclick combofix's window while it's running. That may cause it to stall.
When finished, it will produce a log for you. The report is called
ComboFix.txt.
Post that log in your next reply along with a fresh HJT log AND an update on how the computer is operating now.
