Thanks for the reply.
You used the words "he's spamming". I agree, but after reading the post that you linked to, it seems to me that Avast et al is encouraging people to do that, which is just as bad as Avast employees doing it themselves.
"Share the unique link via social networks or email."
If that's not blatantly encouraging people to spam, I don't know what is. I'm disappointed. Over the past few year's I've recommended Avast to countless friends and family members. I don't know if I'll be doing that anymore.
