Yahoo redirect virus and Chameleon stuck updating


Recommended Posts

About an hour chrome started redirecting all my searches to Yahoo, as well as my home page. I checked the homepage and search setting in chrome and they are unchanged.

I downloaded and ran CCleaner. Problem not solved.

I downloaded Malwarebytes (I had McAfee installed already but I couldn't find a scan button on it) but it refused to open.

I downloaded Malwarebytes Chameleon and it opened, ran through to when it asks to update MBAM and has been sat there for about 25 minutes. Is this normal? Is it working? What else can I try?
