Not if it was downloaded direct from the game page here on itch. The only way that could possibly be true is if someone managed to hack itch.io and replace my original uploaded files with their own infected ones.
I'm an established developer. I've been making games for over 5 years now. If there are any viruses in files, it's because they were downloaded from dodgy sources elsewhere. None of my uploads contain viruses. So if one of my games was downloaded legitimately from my game pages on itch and a virus scanner is saying there's malware in it, it's just a false reading.
I'd like to think most people could tell the game is an actual game just by the sheer number of comments by now.
But cheers for posting bollocks on one of my game pages while I'm ill! Just what I need right now.
