I also suffer from this problem. When I try to launch MTA on Linux Debian 8 Stable, where MTA is installed using Crossover software, I`ve got an error because I haven`t got any antivirus installed. But why I should use antivirus on Linux? Also I tried to install several antiviruses using Crossover and none of them installed successfully.
So for now, I completely unable to play and use MTA! GTA runs well using Crossover...
Please fix it, or make separate version without such antivirus check.
P.S I do NOT want to install Windows for a huge number of reasons.
