Looks like MBA-M did it's job. A question, do you use Lotus or Microsoft Exchange for your mail?
Reason I ask is I see you have a lone McAfee program running and that is McAfee Spamkiller, which, according to their website is exclusively for use with either of those two programs. If you do not use either then you should uninstall it.
You also have a few unnecessary start ups running all the time in the background and these can easily be run manually when needed.
Run HiJackThis again and place a checkmark next to the following;
O2 - BHO: WormRadar.com IESiteBlocker.NavFilter - {3CA2F312-6F6E-4B53-A66E-4E65E497C8C0} - C:\Program Files\AVG\AVG8\avgssie.dll (file missing)
O4 - HKLM\..\Run: [ATIPTA] "C:\Program Files\ATI Technologies\ATI Control Panel\atiptaxx.exe"

Once you have placed the checkmarks then click the Fix Checked Button. Exit HJT.
Reboot the computer.
Run one more full system scan with HJT. Save the log and post it here.
