When Google Tag Manager displays a malware warning, it typically means that Google has found malicious code or activity on your website and has as a precaution disabled some or all of your tags. This will stop the malicious code from spreading or hurting the users of your website.

Google may show a warning message in the Google Search results pages or in the Google Search Console if it discovers malware on your website. Additionally, they might notify you via email of the problem.

It is crucial to act quickly to look into and fix the problem if Google Tag Manager displays a malware warning. You can follow the steps listed below:

1. Check for malware on your website by using a website scanning tool or by hiring a professional to look for malware or other suspicious activity.
2. Remove any malicious code: If malware is found on your website, take immediate action to remove it. To make sure that all the malicious code is eliminated, you might need to restore your website from an earlier backup.
3. Request a review: Once the malware has been removed, you can ask Google to check your website to make sure the warning has been removed and it is safe for users to visit.
4. Check your Google Tag Manager tags: Once your website is malware-free, check your Google Tag Manager tags to make sure they are not the source of the infection.
5. Regularly check your website: Check your website frequently for any suspicious activity and make sure your security measures are up to date to prevent future malware attacks.

You can remove the malware warning from Google Tag Manager and safeguard your website’s visitors by following these instructions.
