Getting false flag on website that I frequent

[Windows7]

This is the website I get this on, it relates to a really old game that I used to play alot, it is an active community and as far as I can tell this site has nothing suspicious about it and have been overriding this error and everything has been fine

This is a Browser Guard Block. I will Alert the proper team to investigate. There is no need for any further action from you at this time.
