Chat invite popping up

duh, i occasionaly miss an evening tv show on the free tv channels we all get.

So I search around and found one the other day on i think it was lime torrent.com

As the show was downloading this little chat window with a head and shoulders pic of

a girl appeared asking if i want to chat, it was from, my connection to the torrent site

using a slightly different url. I run a mac on high sierra which has a load of 'system

prefrences such as Siri and Mission Control which I have turned off or limited as much as possible

Is there anything i can do to stop thesse mesages, adblock doesntn't see them

Symantec doesn't notice them.  Any advice?  Mr Grumpy
