I can't access any site - This connection is untrusted

Được đăng

I always could access every sites I wanted until Firefox 26.0 Version. Starting then, i can't access any site. I can't even do recherches on google, I can't access facebook. I can't even access Mozilla Support. I had to install Firefox 25 to make this post. I'm going to post a screenshot with the error's details: http://gyazo.com/004f051dd9cc7ee9806b9c40e7a038ff.png

Hope you can help me, Thanks

Did you try to click the Get Certificate button?

That should make the View button active.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.


Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
