im pretty experienced in vns and whatnot as ive been playing for one to two years now, and to be honest, in these types of games there's no viruses at all. every game i've downloaded so far hasn't given me a virus. i play on windows and ofc antivirus has popped up a few times but i usually just go on with running it anyway. there isn't any definitive proof about whether there's a virus or not, but consider my words carefully.
