but it says that this is trojan on VirusTotal
Yeah, but if flags as "Trojan.Heur!.02252823" the Security vendor flags it unsafe due to the unsigned exe. This happens with other exe format files too. Here's a example: You are installing google chrome, it's installer opens with no issues. You then install the demo for choicer voicer, your windows defender flags it because it has a unknown publisher. Check it with virus total and you get "Trojan.Heur!.02252823". You wonder why? It's not signed. What's a digital certificate? A digital certificate is a paid/free signature to provide that proves the application is virus-free and a proved app. There's your reason.
so if you guys mean the 0.5.2 version, i had the same issue there but just checked a mark and let it pass the windows defender. After that it Started up with no Problems, i did ran a Anti virus after that and it told me i had 0 viruses so I think its what lurins told before but im no Expert im just here to tell u what ive done and it worked so yea hope that helps.
