I don't know...but I just restarted my computer and tried downloading again and was able to download!
Sorry for the trouble.
I don't have any anti-virus software myself, so it should be standard Windows Defender.
I tried to download “LATEST VERSION - Maw Manor 1.1.0” but could not because a virus was detected.
(I use Edge as my browser.)
However, I did successfully download “OLD - Maw Manor 1.0.2”.
