Hi, I just ran Bitdefender Virus Scanner on my mac and it found MAC.OSX.Backdoor.Wirenet.F in ~/.Install/cracker.app/Contents/MacOS/cracker what do I do? It says the threat could not be disinfected or quarantined do I manually trash it or is my computer screwed? Update: Bitdefender Virus Scanner sucks and upgraded to Avast Mac 2015. Not sure if this is any better but scanning user folder now, and will scan entire computer tonight. Advice on how to deal with this greatly appreciated. Thanks. All my years of Macs I never once had a virus. Update 2: Ugh, Avast seems Bunk messing with all my browser certificiates. What's up with Clam?
