Computer has been infected-my HJT log

Hi guys
Just a new member to this spyware stuff...my IE has been plagued with popups etc and have been receiving a LOT of spam.
Have taken the following steps
1. Updated Norton
2. Downloaded MS XP vital updates.
3. Ran spybot S+D, CWS shredder, TPS3 (all free downloads)
4. Ran Ad-Aware v 6.0 (followed instructions re tweaking etc.)
5. Online scan with Panda online scanner.
6. Installed Zone Alarm as firewall as well as usual ISP firewall.
7. Ran Adawre in safety mode and rebooted and have disabled system restore etc


Is that sufficient? All thest steps identified TONS of stuff that has been cleared. Here is my HJT logfile. Thanks.
