About couple of days now, anytime I try to access an important program on yahoo or google it can appear on the screen: Untrusted Connection, What's that ?

This Connection is Untrusted



         You have asked Firefox to connect

securely to www.pnc.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.


         What Should I Do?
         
           If you usually connect to

this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

Try to Rename the file cert8.db to cert8.db.old in the Firefox Profile Folder.
If that helped to solve the problem then you can remove the renamed file cert8.db.old unless you have user certificates that you may want to export first and import them in the new file.
Otherwise you can restore the certificates by renaming (copying) the file back to cert8.db

Also make sure that your firewall isn't blocking secure connections.

Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
