Getting the "Your Connection is not Secure" message for all websites, including support.mozilla.org
Started late last week. I get the error message for any website that I try to go on. It also comes up when I click on the "Learn More..." link on the error message page.
Additional System Details
- User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E; InfoPath.3; wbx 1.0.0; rv:11.0) like Gecko
What else does it say?
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
