Firefox says Google Services is Secure Connection Failed (sec_error_inadequate_key_usage). It does not give me an option to load the page anyway.

Detailed error message is below shown :

Secure Connection Failed

mail.google.com uses an invalid security certificate. The certificate does not come from a trusted source. (Error code: sec_error_inadequate_key_usage) 

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.

I am using Windows 7 ultimate and I have Kaspersky Anti virus 2013 for internet security.

I am using Firefox version 30.0.

I have tried opening google services with different profiles(guest, administrator,standard user) but each time the same error messages are displayed and google services can not open.

Is this problem is created because of missing authorities certificates? I am using firefox on another computer but it has more authorities certificates than this computer with error message. In other computer google(search, mail, maps etc.) services are working correctly.

It may be Kaspersky intercepting your secure connection to Gmail.

Try to start Windows in safe mode with networking enabled to verify if this is the case.

Do you see this problem with other secure sites too?

I was wrong, it's probably Microsoft intercepting your secure connection.

This may be caused by a windows update - please see http://support.microsoft.com/kb/2965142/en-us#2 for details.
