Link On Premium Page Tries To Install Stuff Into My Browser

I don't see any 'Open' buttons on that page unless I use a web browser without ad blocking, then there are several dodgy looking ads with 'Open' buttons.

I'm guessing it's just a malicious ad you are seeing? In which case, I thought that was par for the course for ads, from all the IT press I've read over the years. Have no practical experience of dodgy ads though myself because I have an ad blocker installed as well as javascript disabled for the major ad networks just to be safe.

As an aside, I did consider subscribing to this forum myself to help support it, but the subscription page went though some 3rd party site went which wanted lots of unnecessary personal info so didn't bother. They can have my money, but not personal info to loose/sell to criminals.
