I take it that you are using Internet Explorer Mike ? I just ran a manual Smart Screen check using IE and the site came up clean. Any chance that there was a dodgy advert on the page?
Thanks for replying, Jim. I don't know if there was a dodgy advert on Internet Explorer or not. It is a mystery but if you say the site is clean then it must be. Cheers.
I checked the site multiple times using 'Tools | Smart screen filter | Check this website' on the IE main menu and it came up clean every time, however on one occasion it told me that the Smart Screen service was down so maybe some problem at Microsoft's end, really don't know but if you see this again please PM me an I will check it again.
It is possible that the site has been reported maliciously, but I would hope not, if it was then it has already been corrected otherwise it would still be showing up on the check.
A couple of weeks ago I had problems with the BF site, every time I logged in, BF would disappear and a home doctor page or something similar would pop up, this happened constantly over a period of a few days until I changed my pop up settings to none allowed for the BF site. So now when I click on a link someone has posted I have to hit the allow once button to view the page. I'm using IE 11 I think, if that makes any difference. Never had problems at all until then.
That's not likely that the site that is doing that, more likely a browser hijack on your own PC, did you get similar things happening on other sites?
