Protect: blocking dangerous pages

Hackers distribute malware that interferes with the browser in order to steal, corrupt or delete information. This malware enters a computer through removable media or the internet. The browser protects you against malware that is distributed through the internet

by warning you if a page is infected.

Before opening a page, the Yandex Browser beta version looks it up in the list of infected pages. Addresses of infected pages are stored in a special database compiled by Yandex and our partners. Any page detected in the database is blocked.

If a dangerous page is not found in the database, but the browser sees it as a threat, the main features of the page are sent to Yandex. There a page goes through a thorough check based on machine learning algorithms. If a page is considered dangerous, it is blocked, and a page with a warning appears. You can:

• Close the page. Click the Leave page button.
• View a copy of the page before infection. Click Safe copy.
• Learn more about the malware. Follow the link to the page that contains full information about the infection.
• Go to the dangerous page. Click Ignore warning.

Take the following security measures:

• Temporarily disable, until you finish browsing this page, potentially vulnerable browser elements: JavaScript and plugins for PDF and Flash.
• After visiting the page, scan your computer with an antivirus or free utilities.

Note that these actions do not protect against infection, but only make it less likely and help with recovery.

If the Yandex Browser beta version blocked your site because it is infected, remove the malicious code. On the next indexation, the Yandex robot will exclude your site from the dangerous list.

You can use Yandex.Webmaster to speed up indexing. To do this, go to the Security and violations and click Recheck. We recommend that you regularly repeat the check for several weeks after infection. This will help detect malware if it was not completely removed the first time.

Follow the security rules to protect your site from infection. If you register a site in Yandex.Webmaster, you will be able to get email notifications about infections and view details of infected pages in the Security and violations section.

To disable blocking of dangerous pages:

1. Tap  → Settings.
2. Go to the Security tab at the top of the page.
3. In the Threat security section, disable the Run security checks on websites and downloaded files option.

Use a similar sequence of actions to re-enable blocking of dangerous pages.
