Cannot Google on Safari but OK on Chrome?

Hi guys,

I am getting a major issue with Google on Safari (am using a Macbook). This message pops out each time I attempt a Google search on the address bar of Safari or the Google webpage.

"We're sorry... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now."

No issues on Chrome, though. I have also tried rebooting the router externally and internally, restarted my Macbook - but still this problem persists. There was also no CAPTCHA box for me to verify myself as a human over a robot.

Does anyone know of a solution to the issue?
