Searchportal problem

[Bonecrusher]

I have a browser hijack problem.
Searchportal randomly hijacks www.imdb.com domain.
I have to manually search searchportal (via Windows Search) and delete it to remove the hijack.
I've made many searches with spybot s&d, ad-aware, avg, spysweeper. They are all updated programs, but none of them find anything.
After manually deleting the searchportal file, It randomly hijack imdb again.
It doesn't hijack one browser, opera, firefox, ie and others at the same time. I can not enter imdb.com with other browsers when hijacked.
There are two (sometimes three) files, one (or two) favicon icon file, and a sql file.
Now, searchportal hijacked another website on my browser. Even I manually delete the searchportal files, I can not rescue this website.

What can I do for this searchportal problem?
