Very interesting article, and one well worth reading.
In the case of CNET, I was totally unaware of its activities until recently when I ended up with the PUP 'MySearchDial' on the computer. Trying to remove this is proving very difficult.
I note also from the article the suggested recommended download websites. MajorGeeks and FileHippo being two suggested 'safe' sites. So its a good job I often recommend these to people on this forum requesting downloads. I now feel that little more happy for offering advice that might not cause future problems for others!.
