Hi and Welcome to TSF
Before attacking an adware/spyware problem with hijackthis make sure you have already run ad-aware SE with VX2 add-on cleaner, Spybot Search & Destroy (with updated database) and CWShredder as these programs will clean a lot of the crap out first. All links to programs are in my signature.
Please go to at least two of these sites and run an online Virus Scan.
Be sure to have the AutoFix box(es) checked.

UPDATE your version of hijackthis and post a new log!
