download.com have for some time allowed scam versions of programs to be listed on their pages. I stopped trusting their site 2-3 years ago. They allow anybody to list programs & do their own reviews. Once upon a time download.com were the ones who did the reviews (unless I am mistaken). My browser gets hit with security issues everytime I go there also. A total loss of respect for their site. I hope as you say they do do something about their scam listings. I made complaint a few years ago, I don't believe anything was done.
There are definitely scam sites in countries such as russia. But also in other countries including the usa. The ones in USA often move & change name after 6-12 months. They often also have several sites up under different names, but same owners.
They take your money & run (when the authorities start to get close to them.)
