Hello

I get the following error when I try to go anywhere google.com bbc.com cnn.com I have cleared cahe uninstalled and reinstalled updated to the latest verison and I can't go any where I am on a win 7 pc hardwire connection

www.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER

There is security software like Avast/AVG, Kaspersky, BitDefender, ESET & sometimes McAfee that intercept secure connections and send their own certificate or their scanner blocks contact or the delete need things. If you are running any of the above software please check their community forum for a work around to apply settings.

These pages are also for the errors you may have besides relating to the above.
