Be on the alert for problems following file downloads from Media Fire in the form of the AV Security Suit scareware. Happened to me last night. Moments after downloading a .ahf file from Media Fire I received a Adobe Icon to update Adobe reader. As soon as I clicked, I received the AV Security Suit alert for infections. Its a scam but they did manage to lock up my desk top computer. Had to boot in safe mode and only open the process that I know are valid. Then run a cleaning tool. Pain in the butt.
