Got some stupid piece of Ad-ware/Spyware on my computer and I can't remove it

I used Ad-aware 6
CWShredder
Hijackthis
Spybot search and destroy
and Registry mechanic

They all found various things and remove them, but couple mins later some of the files are back...

Everytime I open IExplore links me to
res://lqftn.dll/index.html#96676
as homepage

I keep getting this website in background whenever I search on Google
http://search-to-find.com/

And I get various popups when im browsing the web...

Usually using the programs above kills them but looks like I got a clever bastard again...
I got a whole list of Registry files I can delete in Hijackthis but I would prefer not too mess with the ones I am unsure of as some of them are useful... If you think that will solve my problem I will link a list of all the files

OR If anyone has any other programs/solutions (short of formatting my hard drive) Will a system restore have any effect?
