My Mac OS X seems to be affected with the 206trk.info virus.
A couple days ago the Firfox browser on my iMac started redirecting pages. The page will open for a second, then the browser goes to a Yahoo pate. After some checking it appears my iMac is affect with the 206trk.info malware virus. The re directions opens Yahoo and says "DNS Solution Yahoo Error Handler". The browser suggests opening amch.questionmarket.com. I'm looking for information on how to remove this malware. Tried Cleanmymac but it found nothing. Any assitance will be appreciated.
iMac, OS X Mavericks (10.9.2), Firefox 28.0
