  3. Remember, this should only be a temporary fix. Never browse the internet without adequate protection against viruses and other threats.

If the error persists, the problem could be with the antivirus software itself. In such cases, you might need to uninstall the antivirus software and check if the error still appears.

If the error is resolved post-uninstallation, consider switching to different antivirus software. Good antivirus software is updated regularly to protect against the latest threats and to ensure compatibility with other applications on your PC.

 Important: Make sure to turn the antivirus on instantly after trying the fix, as keeping it turned off for a long period will put your PC at risk.  

Modify Server Revocation Options

Your system checks for certification revocation to ensure the credibility of the server. However, this setting might sometimes lead to security certificate errors. Modifying the server revocation options can potentially resolve the issue.

Here’s a step-by-step guide:

  1. Press the Windows Key + S simultaneously. This will open up the search bar.
  2. Type “Internet Options” in the search bar and select it from the drop-down menu that appears.

Reset Your Browser To Default Settings

If all else fails, restoring your browser to its default settings might just do the trick. This method will clear any configurations that may be causing the security certificate error.

Here’s how you can do this:

  1. In your browser’s URL bar, type “chrome://settings/” and hit Enter.
  2. On the left side of the page, you’ll see an option for ‘Reset and clean up.’ Click on it.
  3. Now, on the right side of the page, choose ‘Restore settings to their original defaults.’
  4. Finally, click on the ‘Reset settings’ button to confirm.
