Firefox Hijacked

Hi, I've had this issue as a recurring problem, unable to find a solution anywhere. I appear to have acquired some kind of malware, haven't been able to find the source after hours of looking. I've run numerous virus scans, spyware, malware, and nothing can detect it, and, needless to say, remove it. I'm at my wits end with this issue, and was hoping I could get some help from any other people. Two heads are better than one. Thanks in advance.

You haven't really explained the issue and what exactly is happening.

I got so engrossed in explaining my failure, I forgot to explain the issue. Wow.

Basically, whenever I click a Google link (usually restricted to the first 2-3 on the page) after searching only from the bar in the top right, I redirect to some f1.ozonenews.com site, which redirects me to various virii, malware, and other forms of unwanted junk. I'm really not concerned about that as I have protection, I just hate having to cache the page from Google and reload the page from the cache. Any help is useful.
