Emisoft no 1 on secutrity but very expensive has this to say. Lists the Pups which are unwanted programs snuck in with a down load you wanted all too often and if you miss the small print you get these PUPS.

 Its a good list to keep in your data to check before downloading.

Also Emisoft have On Line Armour the best firewall imo and lots of others but expensive too - No actually my price FREE but you have to look for it and go for free version after downloading the firewall alone also in small print when opened.

BTW most of these download sites are loading.

One that is free of these is www.majorgeeks.com

so bookmark it for future

and leave CNet and the others even File Hippo alone all are too busy being greedy - seems to be very few trustworthy people about these days.
