Strange Bumps in the Night

Hello folks,

After doing a SpySweeper scan, this adware comes up: Default-homepage-network Hijacker
HKEY_CURRENT_USER\software\microsoft\internet explorer\main || search bar.

I get SpySweeper to delete it, then I get an Alert: SpySweeper has detected changes to Internet Explorer's default pages, such as the Search page. To restore original pages, click restore.

I do this, but a few seconds later, the Hijacker reactivates itself and shows up on my follow-up SpySweeper scan, AGAIN. Repeat, rinse, repeat, rinse . . .

I have freshly scanned for viruses (Norton Anti-Virus), SpyBot and Webroot SpySweeper. I have Zone Alarm and Norton on at all times. My email provider (Postini through SaskTel) stops almost everything for months at a time; but yesterday two emails got through, one with domain "sourceonetek.net" and one other that looked legit (I've deleted and forgotten its domain) which had a Word.doc attachment that I opened (stupid me). Because of that, small weird things made me do a series of scans. A bunch of spyware/adware came up, I got rid of them, but this last one just WILL NOT GO AWAY.

Also, I've set msconfig at 'selective startup' because I don't know how to safely get rid of the adware/spyware/virus listings. Can you tell me how to clean that up, too?

You all will be my help in time of need. Here's my log, made after a reboot after fresh scans:
