Hey. According to some reddit posts that I found Avast likes to falsely report files that are not malicious.
Someone suggests updating Avast fixes it but that was 3 years ago so I assume you dont have a 3 year old version lol.
You can also use the build in windows defender to scan it and a website like VirusTotal which runs a file through multiple scanners.
I think its a false positive but I understand if you don't want to play a game where your Anti Virus reacts to it.
