Simple problem yet persistant

I am having some stupid malware problems with my computer. I can usually hunt these things down but this one is ellusive. I did follow the "getting started instructions" to the letter but the Panda Activescan window blithely closed soon after completing. It did however tell me that it didn't find anything. Heres my info:

Specs:
Gateway CX200X, Tablet
1.7 GHz Pentium M
1 GB Ram
Windows XP Tablet with all updates
Panda Platinum Internet Security
Zone Alarm Free Firewall

Symptoms:
-Started with browser Hijack and popup windows. That was remedied several days ago.
-Popup windows returned today: ran Ad-aware and Spybot removed popup window problem
-Icon in tasktray that alternates between red circle crossed out and a green broken circle. It reads "Virus Alert!" when moused over.
-Every once in a while an alert window pops up with a malware warning that I don't recognize wanting me to download removal software.
-Spyfalcon randomly installed but was removed via "Special Removal Procedures" on this forum.

--So basically all that is still wrong is the tasktray icon and the alert window.
I am worried that the browser Hijack will return as it already has.

Scan Results:
The only scan that returned any hits was the Bitdefender with three trojan.downloaders and one win32.browserhijack. All others found nothing.

Here is my HJT and bdlog:
