Overview
Google sometimes shows an "unusual traffic from your computer network" message and asks you to complete a verification. It appears when your connection sends automated-looking requests — often from malware, a misbehaving extension, a VPN, or a shared network. This guide explains how to resolve it.
Key Takeaways
- The message is a protective response to automated-looking search traffic.
- Common causes include malware, aggressive extensions, VPNs, and shared IP addresses.
- Completing the verification usually restores access immediately.
- Persistent errors point to malware or a network-wide issue.
First Steps
1. Complete the verification challenge Google presents to confirm you are human.
2. Disable any VPN or proxy temporarily and reload the page.
3. Turn off browser extensions one by one to find a culprit.
4. Restart your router to obtain a fresh IP address if your provider allows it.
Scan and Clean
1. Run a full scan with Windows Security or a trusted anti-malware tool.
2. Remove any unwanted programs and suspicious extensions it finds.
3. Clear your browser cache and cookies, then reload Google.
4. If on a shared or office network, ask the administrator whether others triggered the block.
Note: On shared networks such as offices or campuses, one user’s automated activity can trigger the message for everyone on the same public IP address.
Troubleshooting
Problem: The message returns immediately after verifying.
Solution: Scan for malware, since infected software may be generating automated requests in the background.
Problem: It only happens with the VPN on.
Solution: The VPN’s shared IP is flagged; switch servers or disable the VPN while using Google.
Problem: Every device on your network is affected.
Solution: The issue is network-wide; restart the router for a new IP and check for infected devices on the LAN.
Problem: A browser extension seems responsible.
Solution: Remove the offending extension and only reinstall trusted ones from official stores.
Conclusion
The unusual-traffic message is usually cleared by a quick verification, but recurring errors are a signal to check for malware, extensions, or VPN behavior on your network.
