Hi MohammadAhmad5
Welcome to Microsoft Community.
Based on your description, I understand that every time you open Chrome you encounter an error message from Google prompting that your network has detected abnormal traffic. I understand very well how you feel!
Please allow me to explain to you that this reported error does not seem to be generated due to the Windows system, but rather by the Chrome browser. It shows that anomalous traffic has been detected from your computer's network, which often happens when Google thinks that there may be automated tools or bots trying to access its services.
This step is essentially a “validation step” used by Google's servers to verify that the person accessing the service is a real person.
Because it is assumed that if this verification is not set, the server is likely to be subject to a DDOS attack, where the same server is accessed by different network devices from all over the world, ultimately leading to a server crash, the addition of the verification step effectively prevents bots or automated tools from accessing the service in a malicious manner.
I will give you some advice that I hope will help. But assuming the problem still exists, maybe we can try to contact Chrome or google's support team or network ISP and ask them to detect your network environment through the tools officially provided by Google or ask if it is possible to add your environment (IP address) to the whitelist manually.
Option 1: Let's try to go through some simple steps to see if we can solve the problem.
- We'll try rebooting the router. If your ISP uses dynamic IPs, sometimes just rebooting the router will assign you a new IP address.
During the reboot process, I recommend that you turn off your router and wait 15 minutes before turning it back on. Avoid network configurations and the router's built-in chip not being completely refreshed and rebooted.
- If you are using or have used a VPN or proxy server on your computer, at this point we need to temporarily disable them to see if the problem still exists.
After all, this problem is caused by Google detecting our network environment and mistaking it for abnormal traffic.
If necessary, we need to try to cleanly uninstall the VPN and Proxy. cleanly uninstalling is to prevent configuration files and registry residuals from causing the problem to still occur.
- We will try to completely reset the network from the command line to see if the problem still exists after the reset.
Click “Windows Logo Key” to open the search bar -> Type “cmd” in the search bar and open it with administrator privileges -> Please enter the following command
ipconfig /release
ipconfig /renew
ipconfig /flushdns
ipconfig /registerdns
netsh int ip reset
netsh winsock reset
netsh winhttp reset proxy
- We tried entering the system in Safe Mode with Networking and opened Chrome to see if the problem persisted.
Since Safe Mode only uses a minimal set of drivers to enter the system, it can help us effectively troubleshoot the possibility of problems due to third-party applications, driver conflicts, etc.
For safe mode, you can refer to: Windows startup settings - Microsoft Support (select “Safe Mode with Networking”)
Option 2: We tried clearing the browser cache and cookies and resetting the settings to see if the problem persists.
As I am using Microsoft Edge browser in my work environment and am unable to use Chrome.
So here I will give you some steps using Edge as an example, the steps in Chrome should be more or less the same, though there may be some differences.
- Clear your cache and cookies.
Open Edge browser -> click “...” in the top right corner. button -> “Settings” -> “Cookies and site permissions” -> “Manage and delete cookies and site data” -> “See all cookies and site data” -> “Remove all”.
Disclaimer: Your browser automatically saves temporary internet files to help pages load faster. Clearing this cache will sometimes fix website issues. Please back up all your personal files first, such as Favorites, to ensure you do not lose data.
- Reset your browser settings.
Also in the browser settings, on the left sidebar, select “Reset settings” -> “Restore settings to their default values”.
Option 3: Sometimes it is possible that the problem occurs due to abnormal traffic generated by some malware.
We try to run a full scan of your computer with Windows Defender or some third-party reliable antivirus software to see if there is some malware using your network and generating malicious traffic.
Option 4: If you are using any scripts or automation tools, consider limiting their frequency or disabling them.
It is also possible that automated tools or scripts may generate some abnormal traffic while running, which will eventually be detected by Google servers.
Option 5: We tried using another browser or another device in the same network environment (e.g., another computer, cell phone, etc.) to see if the problem persisted.
This step helps us to narrow down the problem to see if it's limited to Chrome.
In addition, assuming that your troubleshooting reveals that the issue is specific to Chrome, I would recommend contacting Chrome support to provide you with specific tools or assistance in troubleshooting. If you find that the problem occurs in other browsers or on other devices, I recommend that you contact your ISP (Internet Service Provider) and ask them to check their network logs for malicious traffic.
I sincerely hope that the above information will help you. Please feel free to contact me (Photos related to the question would be great!).
I look forward to hearing back from you.
بارك الله فيك. Best Regards
