How to fix Microsoft Edge Critical Error

When you see a Microsoft Edge Critical Error, your browser or system might have been infected by a virus, malware, or adware. Viruses, malware, and adware can enter a user’s computer in different ways, like:

If you download software from a third-party or untrusted website instead of the official website and install that software on your system, your system may be infected by a virus or malware.
When you click on the ads displayed on websites with an insecure connection, i.e., the websites that do not have a green padlock icon, the chances of being infected by adware become high.
Sometimes, viruses or malware enter a system by installing addons or extensions on a web browser.

For some users, this error message appears while surfing the internet. If you see this pop-up on some particular websites, this might be appearing due to malicious advertisements. The purpose of malicious advertisements is to spread malware through the internet and compromise the users’ systems. Therefore, you should avoid visiting such websites.

If your Edge browser has been locked due to this error message or if you are getting this error message every time you launch Microsoft Edge, the following troubleshooting guidelines may help you fix the problem.

Run antivirus and antimalware scan
Uninstall the recently installed software
Remove the problematic extension
Reset Microsoft Edge

Below, we have explained all these methods in detail.

1] Run antivirus and antimalware scan

Antivirus software protects a user’s computer against threats. Install trusted and reliable antivirus and antimalware software on your system and perform a full system antivirus and antimalware scan.
