Avast Threat Warning During Pale Moon 26.1.1 Install

This is very strange and I haven't seen any reports about this issue.
During the install process for Pale Moon 26.1.1, Avast anti-virus ver 11.1.2253 stopped the process with a Threat Alert.

Has anyone else had a similar event or know anything about this?

 

Upload that setup.exe file to VirusTotal.

It's clean, my fault for not having used Avast since mid-December last, prior to that, all the PM test/beta/release versions would have been checked out by them days before public release.

 

VirusTotal scan results HERE

Even after adding it as an exception twice, Avast still coughed on it.
I fully removed Avast, reinstalled, then ran Pale Moon install with Avast default settings.

Whatever it was, it's fixed now.

Thanks.

 

When I have such a problem with Avast, I disable it for 10 minutes.
