Which antivirus software are you using? I'm curious.
Even i would like to know the anti-virus software you are using.
Me three! But I'll go out on a limb here and guess that it's either Norton of MacAffee lol...

Wrong on both of them will never use them B!tches lol
Am using avast internet security. However it did not pick up on that. It was malware bytes that kept stopping and blocking it on the ports.
Malwarebytes is a great scanner, but it's real-time protection could use some work. I have it detect false-positives all the time on customer's machines. I've actually stopped recommending the paid version until it gets a little more polished.
