I have started to get the message "Content was blocked because it was not signed up by a valid security certificate" whenever I go to a site. I am offered an option to continue to the site although it is not recommnended. It also happens sometimes within a site when I am going to a different area within the site. Sometimes I get straight to the site but some of the pictures are blocked - although I can choose to unblock them and they then show.
I have tried incresing the security settings to high because it said that it was happening because my security settings were too low but that hasn't helped.
Setting your security settings to high will only make it worse.Any bad sites I go to A squared opens up and tells me to allow or deny,I will always deny it unless I know that it is a genuine site.And even if you deny it you can always go back to A Squared settings and allow it again. Is it Microsoft or one of your other security programs that is giving you the warnings.
