"Unusual traffic from your computer network" notification
What to do when Google detects automated queries on your network
When Google detects that a computer or phone on your network may be sending automated traffic to Google we may show the following message: "Our systems have detected unusual traffic from your computer network."
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 we know you're a human, not a robot.
How to troubleshoot if you did not see a CAPTCHA
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. Malicious software, sometimes bundled with other free downloads without your knowledge, can trigger Google to show this message. Visit our security information site for some well-known programs that can detect and remove such applications.
If the suggested programs don't resolve the problem, you might want to try an advanced troubleshooting program such as HijackThis.
HijackThis lets you view programs installed on your computer and easily remove malicious ones. We're not affiliated with HijackThis and cannot vouch for it ourselves however many other users have found it useful. After scanning your computer with HijackThis, you can determine which programs to remove. Make sure to be cautious, as you do not want to remove legitimate programs from your computer.
After using HijackThis, we suggest that you update and run the three applications listed below again. Although you've already run these programs, doing so after using HijackThis often exposes additional files.
- Contact your network administrator. If you tried the steps above and haven't resolved the issue, it's very likely that a user or a computer in your network is sending automated traffic to Google. Your network administrator may be able to locate and shut down the source of the automated traffic; feel free to refer them to this page. Once the automated traffic has stopped, the ban on your IP address should be automatically lifted.
- If the problem persists, your network administrator should contact us. If your network continues to experience this message in error, please send us additional information.
