Google notification error "Unusual traffic from your computer network"

As the notification say, "your computer or network may be sending automated queries".

The error page most likely displays a CAPTCHA (a squiggly word with a box below it). To continue using Google, type the squiggly word into the box - it's how the site know you're a human, not a robot.

If you don't see a CAPTCHA image or if you continue to encounter the CAPTCHA over and over, try these steps in order:

• Check for malware on your computer. See this video in this sense.
• Contact your network administrator
