When I try to go to any sites like Google YouTube .etc I receive the following message:

'Your connection is not private'

'Attackers might be trying to steal your information from www.google.co.za (for example, passwords, messages or credit cards).'

What does this mean? I am not able to access any pages other than stickpage. Pls help

More info:

www.google.co.za normally uses encryption to protect your information. When Chrome tried to connect to www.google.co.za this time, the website sent back unusual and incorrect credentials. Either an attacker is trying to pretend to be www.google.co.za, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.
