First of all I don't think automatic windows update has anything to do with it. When my pop-ups started I had Win XP sp1 (with updates turned off). I tried to install SP2, but that didn't solve the problem (I also have tried everything you guys have done plus lots and lots of firewalls, spyware stuff (also Giant anti Spyware, recently aquired by Microsoft [somehow i think that's connected with this]). SP2 slows down my internet surfing so much that I removed it again. Now I'm back at Win XP SP1, automatic updates turned off, and stilol the pop ups!
It all started with a virus like application 0catyellowpages.com. But the the problem seems to be polymorphic since it has changed over the last 4 days.
My pc connects to these webpages when teh pop-up shows: http://69.50.160.100...php?acc=acc0001 (custblock.intercage.com)
and: xlstcache.alexa.com
This is the log of the windows firewall:

I will try to rinstall IE 6.0 like you did. It's the only thing I haven't tried yet.
