Remove the message from your site

The "This site may harm your computer" notice won't be removed until the webmaster of the site takes action.

Try these steps to fix the issue if the message is showing on your site:

  1. Register and verify your site in Google’s Webmaster Tools.
  2. Sign in to Webmaster Tools and check the "Security Issues" section to see details of sample URLs that might be infected. Fix the security issue that allowed your website to be infected. Otherwise, your site is likely to be reinfected.
  3. Read our resources for hacked sites for detailed information on how to fix your website.
  4. Request a review in the Security Issues section in Webmaster Tools when your entire website is clean and secure. After we determine your site is fixed, we'll remove the "This site may harm your computer" notification.
