svchost.exe using up 99%CPU

Hello, I've been having a lot of trouble with my computer lately, and it all seemed to start when I switched over to a new dial-up connection here in Spain. My ISP (Wanadoo) made me download a new dialer to access the internet and it all went haywire from then.

I apparently had some spyware on my computer from before but it was not causing any noticeable nuisance, but now whenever I get on the internet, a few minutes after I connect, a svchost.exe process starts that uses 99% of the CPU. When that happens, half of the times I am able to keep surfing, although slower, and the other half of the times I can't open up any new pages. In all of these cases, it is impossible to get off the internet unless I manually reboot.

I am running XP pro, with Panda Titanium. I am running the antivirus at least twice a day, have dowloaded and run Ad-Aware, Hijackthis, the Symantec FixWelchia tool (I thought this could be the Welchia worm, but nothing was detected, maybe it's a new variation?). I have managed to get a lot of trojans, malware, etc. off my system, but this particluar problem persists. Panda antivirus also seems to detect and neutralize a lot of W32.Sdbot.xxx worms lately, maybe this could be related?

Many thanks in advance, here is my log, through the HijackThisAnalyzer.

PS funnily enough, things seem to be ok if I get on the internet through my old account, maybe this can give an indication of what's going on.
