You are running plenty of spyware removal programs but you don't seem to have a working firewall to stop them comeing in. It could be that you are cleaning the machine only to have more malware appear as soon as you go back on line.
If the XP firewall is not working you should get something else installed until you can fix it.
Zonealarm is quite easy to use and there is a free version,

I would download that and install it.
Go online and update all of your spyware tools and windows if you can.
Run your spyware tools again.

That should clear out what you've got and stop anything else coming in.

You might also want to try Spyware Blaster:

It is another tool which acts to stop spyware coming.

Additionall you might want to add one of the anti-spyware HOSTS files that are available on the web. Adding one of these might help to stop the spyware calling home if it does get in and downloading further nasties.

IF after all of that you still have lots of problems it's probably worth reformatting the machine to give you a clean sheet to start from again. If you are doing that keep a copy of zonealarm on a disk and install that before you go on line again.
I've personally had a machine compromised within 2 minutes while I downloaded a firewall as a first step. I think it happens even faster now. So get the firewall on before you do anything else.
