Question : Internet Explorer - Links redirecting to strange sites

I'm running IE 7 on Windows XP, and I've got a strange spyware or malware problem, I think.

If I search for something on Google or Bing, and I click one of the results (which are actually on popular websites), sometimes - not all the time - it redirects to some strange website with products, like I'm infected with affiliate spyware or something.

Though I've run SuperAntiSpyware, Malwarebytes, Spybot, Trend Micro, Sunbelt CounterSpy, and they have found no infections.

After I noticed this issue with IE, I installed FireFox, and the issue is happening there apparently, too.

I've attached a hijack this log in case this is helpful for someone to help mew.

Answer : Internet Explorer - Links redirecting to strange sites

I saw this a few weeks ago. If it is the same one, disabling Google toolbar stops the redirects. I got it out with ComboFix.
Please follow the instructions carefully.
