What do you mean ? i scanned the games files with windows defender and it found nothing.
Okay I don't know much on viruses & trojans but I think the download has been infected for a few hours. Me & Fading both got the Trojan at the same time, downloading MA at the same moment. I tried downloading now and I haven't gotten anything, no response from neither Windows Defender nor Avast. Either has been a false alarm or smt that has resolved itself, my bad on that one!
I looked up the Phonzy thing, and Google spat me out a bunch of things, some of which claim it is a false alarm from Windows Defender, others it isn't anything to be worried over. I'm assuming in this case, it was a false alarm.
I saw someone on reddit give a link to a page called VirusTotal, which you upload a file to the site and it scans whatever you give it. Though I haven't used it myself, I've seen people use it in the past, so I know it's real.
You might have downloaded something that wasn't the game at first, so I would have no idea.
