Not sure if you are into Mu Online Development, but any viruses inside the main.exe are not viruses, but false positive Trojan signature or whatever virus. The reason that is detected as a virus is because inside the main.exe are happening some "Illegal" changes into the memory, such as loading libraries, functions being hooked or detoured, etc.. so the game can be adapted to the server administrator needs without having the main source code.
It's safe to play on most servers I would say, but yes, most players do have an antivirus and maybe they don't wanna disable it.
There's no MAIN source code, so no one can develop a correct main.exe without false positive antivirus reaction.
NOPE thats not the case. I play MU Online from season 1 on global and i remember when almost every client was virus free now its almost impossible to find a client without viruses.
It comes not only to main.exe which sometimes is virusfree but then many DLLs have trojan.wacatac or trojan.zexaf trojan.zedaf or another backdoors! And dont tell me its false positive cause when you reverse engineer them they are trojans cause i tried it many times on virtual machines !
Provide a MUOnline Server link and I will prove you theres a VIRUS not a falsepositive there, otherwise i could even pay to play VIRUS FREE server! Thanks
PS. Old CLEAN clients mostly on IGC had only IGC.dll which gave any alerts on virustotal which was IGC.Pua which really isnt a virus, but its impossible to find such one today!
If You are able to provide any server using CLEAN CLIENT give link and I will post results of my check here, THANKS
