Virus alert / desktop hijack / clock screwy

I had 'VIRUS ALERT' imbedded into my clock, and it displayed military time. I removed that partially with Spybot. Now, the 'VIRUS ALERT' is removed, but the clock is still in military time. At one point these infections broke into my safe mode, and begin affecting things. Used various virus programs since my Norton contract has lapsed. The Norton Program is also unable to be removed from the add/remove program section of the Control Panel. Am currently using Avira evaluation. I scanned for the bad wares and removed many with AVG & Malwarebytes, however I restarted into safe mode after scans in a couple instances. Not sure if that is going to affect my startup, but the computer is STILL infected since it starts up very very slow now, and I noticed that the browser is hijacked in a couple areas.
One, where you can expand your icons at the bottom right, and the arrow is missing.
Two, where you can hit the green 'Start' in the bottom left, most preferentials such as quicklinks to folders are missing including, 'My Computer'.

I cannot update to most other virus programs on that computer right now since I am Windows XP Home SP1, and most viral programs require SP2. Arrrggggh! mad.gif

Included attachments in the following order: Pandascan log, Malwarebytes log, & HijackThis log.

PLEASE HELP :cry
