Well, it would seem that Ad-Aware SE believes that the url in my favourites that points to:
http://www.oscars.org/awardsdatabase/index.html (the Academy Awards Database) is a "Possible Browser Hijack Attempt"
erm. I know that the Academy Awards have their critics, but I'm sure they wouldn't hijack a browser

So, I think we have a false positive here.
