It appears that I have some malware on my Windows 7 computer that hijacks only certain urls on Firefox. It specifically happens when I google or use yahoo to search and then click on certain urls in the search hit list. It seems to take me to "mcengine.com" and/or "newsfudge.com". I am attaching the hijackthis logs. I've tried a number of things already including malwarebytes (finds nothing), superantispyware, etc. Thanks in advance for your help.
