Is there a fix for Firefox being auto-redirected to known attack site from every new Google search?

Question

Every time I do a Google search, the first link in that search clicked will direct me to a known attack site at http://64.111.212.229/ (URL followed by lines of gibberish code). It will occur only on the first link of any new search attempted.
My AV (Symantec Corporate 10.1.7.7000 version 12/8/2010 rev. 2) does not pick up any malware.
The problem does not occur in Google Chrome.
Does anyone have a similar problem and/or solution?
My Firefox: 3.6.13, OS: Windows 2003 Server Standard SP2.

@sergej0363: Well, nothing to stop you with your solution. I agree that some anit-spyware can be a bigger nuisance. Having said that, the problem you described may or may not look like a spyware problem though. I have found Spybot S&D to be quite serious and efficient, trusted by many.
It is not true that Mozilla is targeted specifically, although some browser-specific attacks may indeed occur, most often with IE. Assuming that your problem is indeed malware/spyware related it may be a matter of time until another browser is affected. And by no means Mozilla doesn't care. It actually has features like "block reported attack sites" or "web forgeries" when turned on. And Mozilla's OSS development model is usually considered to produce better security. But all this cannot always prevent e. g. drive-by infections or accidentally installing a spammer add-on.
As always, the classical triple precaution anti-virus, firewall, anti-spyware should help, besides keeping browser and OS software up to date and general.
