I was sent a link via Facebook that McAfee Security Center flagged as a Koobface worm, but it didn't appear to catch all of it. My browser has now been hijacked - attempts to go to MalwareBytes.org blocks the access, redirects it to an ad, or redirects it to a site that looks like a Virus Scanner (I believe it was called System Security). I also cannot update Malwarebytes Anti-Malware, and I'm not sure if McAfee is working either. I installed MBAM and the latest updates i could find, but when it runs now it doesn't find anything. Any ideas? Thanks, Keith
