What should I do if a site security threat is found?

Yandex.Webmaster checks your site daily. If it detects a security threat or violation of search engine rules on the site, a message appears on the Diagnostics → Security and violations page. In this case, follow these steps:

When you solve the problem:

  1. Make sure the problem is fixed. If the service re-detects a threat during verification, you will not be able to report fixes for a month. After that, this period will increase up to a maximum of three months.
  2. In the Yandex.Webmaster interface, go to Diagnostics → Security and violations and click I've fixed everything. This will give an additional signal to the Yandex algorithms that the site needs to be rechecked. If the check is successful, the restrictions will be lifted over time and information about violations will no longer be displayed.
