Last week, my anti virus software (bitdefender) expired, and I was without one for a couple of days. By now I have reinstalled the updated version and it is fully operational, with no security issues or messages or updates waiting to be installed. It might be a coincidence (but I think not), but since a couple of days, Mozilla firefox no longer allows me to visit google.com/be (I'm Belgian); it claims it can't confirm that the connection is secure. I most often use the search engine duckduckgo, but would still like to be able to use google if need be! I have tried running Mozilla Firefox without add-ons and there was no difference. Every time, I get this message: "This Connection is Untrusted You have asked Firefox to connect securely to www.google.com, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. ..." Please can someone help me? I run Windows 7. According to the action center, everything is running normally, and internet security settings are "set to their recommended levels". That's as far as my internet problem solving abilities go.. Thank you so much!
