Please help - lots of viruses that no antivirus is removing

HI there,
I managed to pick up a handful of horrible viruses/trojans that nothing is removing. ABG Grisoft recognised them at first, but wouldn't remove them - now it doesn't even recognise them. Trend micro did the same, and Pandasoft recognises them, tell me the solutions is to delete them when I'm offered that, but it doesn't actually offer this and the report states that the files were not disinfected. When I searched this website it doesn't seem to recognise the names I have. According to the Pandasoft log the details are as follows:

Exploit/Codebase X in my temp internet files
VBS/Psyme C in temp internet files
Trj/Lowzones.HE in windows/system 32
Bck/Pidor A also in windows/system 32

It also tells me that I have an enormous amount of adware that AdAware hasn't recognised, nor has Microsoft's Beta AntiSpyware. I also downloaded an antivirus program called TCMonitor which also seems to be identifying the viruses but I cannot figure out how to remove them using this software. In fact that software is kind of driving me nuts. TCMonitor tells me:

Virus identified Jave/ByteVerify Infected, Embedded object (2 are in temp interent files, another 2 are in C:\RECYCLERS)
Virus identified Java/ByteVerify Infected, Archive (1 is in the temp interent file, 1 in RECYCLERS)

As far as I am aware my browser has been hijacked - my homepage has been reset and I cannot do any searches (it brings up porn searches). If it has done more than that I am not yet aware of it.
I use Windows XP, (have SP2) with Zonelabs, AdAware, Grisoft AVG Antivirus and Microsoft AntiSpyware. But still I can't shift these buggers.

PLEASE HELP!!
Thank you very much.
