Welcome to the club.
Norton Security blocks URLs with the word "advertising" in them. Hurting my web site traffic & annoying my customers. Apparently "advertising" is a dirty word to those idiots.
The usual shotgun approach to any problem. Jerks.
I wrote them about it. I expect an answer any decade now.
Ahhhh, you're an optimist I see.
It's even worse than that. It also blocks images with "advertising" or "ad" in the file name. This is a piece of crap software sold by a piece of crap company.
