Following my previous message above, I’ve examined a swathe SM 1.11 zip files. It appears that all files after “sourcemod-1.11.0-git6947windows” trigger this virus/malware alert in Windows Defender. However, SM zip files before git6974 seem unaffected. I suspect that these alerts are merely false positives occurring during the download process.
I would greatly appreciate if someone with expertise could verify this. Alternatively, if there’s an existing discussion on this topic, kindly direct me to it. Despite searching online, I’ve yet to find relevant information on this issue.
EDIT: So this link is as good as it gets then >>
