disappearing homepage, popups, backdoor.small

[Servant1975]

I think i've been hijacked and infected. Everytime I open IE my homepage goes to about:blank, and AVG says BackDoor.small.3.BI and trojan Downloader.Agent.7.E detected. When I do a yahoo search a search pop-up comes up, and I keep getting pop-ups from Only The Best.

I've run AVG, adaware, and spybot search and destroy, nothing helps.
Thanks for the help.

Here is my hijackthis log:
