IMO if you want to avoid the risk of getting a PUA or PUP in the installer, then you shouldn't use Softonic, and CNet/download.com. The best is to go straight to the vendor/author's website, the sites I use in order are Majorgeeks, Softpedia, etc....
That's a PITA you will have to live with as ESET is just doing what you expect it to do when you got the PUA and/or PUP detection enabled, stopping them at the front door.
I also want to say thank you to you all. I too am not a cyber-genius, just a curious home user. It is just these kind of exchanges of information that keep me coming back here for more! (Softpedia is my go to place, I'll have to take a look at Majorgeeks...).
Sincerely,
