Sorry but I can't enter into yet another discussion about this (too many today) but if you see what I did and the reply from staff you see that it's even harder to opt out.
I will chat about what it took to get rid of stuff.
I received a notice from CNET that my Avast software had been updated, and I was offered a download. When I did, I found that CNET had added Google Chrome to my PC without my knowledge and without asking if I wanted it (I did not). I really have to question the ethics of such a methodology. When I tried to send an email to one of the editors to complain, I could not get through. Six times the site did not accept their security code. Suggests to me that CNET does not want to hear from its clients.
