This is very suspicious. The detections usually come when it's packed so the fact that this is not packed and have this much AV-positives is quite sus.
I've coded a multiclient before (and it's still active now btw) but never got this insane amount of detections because a multiclient, supposing it's not doing some dark **** behind the scenes, would never get this much cuz it only touches a few apis.
GoogleUpdate? Svchost? That's a classic malware strat. Pretending to be an OS while recording key inputs from behind the scenes. Or if this guy was an ******* enough, probably a RAT which can control your PC, record inputs, listen to your mic, and watch you using your camera.
Oh wow, powershell. Another classic malware strat. Also another another classic malware strat, The Scheduler. This guy's virus needs to run when restarted and there's three ways to do that. The Move-to-Startup folder technique, the Add-To-Registry technique, and the Task Scheduler technique.
So uhh, you said it WASN'T packed right? Oh yeah what a great file, it has no .text section (which for the people who don't know coding, it's where the assembly code is)... which compiler did you build this on, MSVC 2089?
So uhh the verdict..... this is definitely a malware. 100%. I recommend people who used this to open your task scheduler, remove this guy's scheduled task, and then run a full scan of antivirus.
By the way I also sell a multiclient, it's 100% safe (because i need money). It's $7.56 a month and it's not just multiclient, you can also get cheats for both official cabal and private server cabal while supporting our lord and savior Yukikaze-sama.
