When I access this thread - https://community.logos.com/forums/t/198584.aspx - Norton flags an intrusion attempt as below. I can access any other thread without any problem.

The details behind that are (shown in two screenshots as it doesn't all fit in a single window)


Does anyone have any idea what this means, why it only is triggered by accessing that particular thread, what - if anything - I ought to do about it?
Update: That thread has now gone onto three pages. Accessing the first or second page flags an issue but accessing the third does not!
Thanks, Graham
