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 for details.
