hijacked for weeks now nothing seems to fix it

Dudes:

I am cresfallen. I've tried the following programs all to no avail:

* Hijackthis
* SpySweeper
* Spyware_Blaster
* Start Page Guard
* Adaware
* Spybot
* Registry Mechanic

Whatever I do to fix the problem, the whole thing simply reappears on bootup - here's the whole gruesome story:
