What happened?

When installing Prometheus (and I assume other apps), Trellix (McAfee) blocks the detection script from running due to a suspicious double filename extension.

Looking at the NSI script, the temp name generated includes a .tmp extension, then when the script adds a .bat to the end of this, it ends up being [tempname].tmp.bat, which my antivirus doesn't seem to like.

Version

(Dev) 2021.12.03

What version of Windows are you seeing the problem on?
