Protect: blocking dangerous pages

Attention. Yandex Browser warns you when you navigate to a dangerous site, but it is not a full-fledged antivirus product. However, Protect technology defends your browser against computer threats that antivirus programs do not block. We recommend using both for full protection.

Why Yandex Browser blocks infected 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.

How blocking works

Before you open a page, Yandex Browser checks it against a 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 copy of the uninfected version of the page is stored in Yandex, you can view it. To do this, click the link to the page with full information on the threat, and then click Safe copy.

The page with full information on the threat also provides information on what malware was detected on the page.

You are allowed to ignore the warning and visit a site with dangerous content.

Attention. However, we strongly recommend that you don’t visit a website with dangerous content. Malicious codes can infect your computer or give hackers access to your personal information and electronic payments.

If you must open a dangerous page

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.

Interaction with antivirus software

The security mechanism in Yandex Browser doesn't conflict with other security applications (anti-virus software and firewalls). If antivirus software is installed in the system, it can detect malware sooner than the browser. In this case, you will see a message from the antivirus rather than the browser.

If Yandex Browser is blocking your site

If Yandex Browser blocked your site because it’s infected, delete 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, click the Recheck button in the Security and violations section. 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.

Disable protection

Attention. If you want to disable blocking of dangerous pages, you will have to completely disable protection against malware and malicious sites in the browser. We strongly recommend that you don’t do this.

To disable blocking of dangerous pages:

  1. Click  → Settings.
  2. Go to the Protect tab at the top of the page.
  3. In the Threat security section, turn off the Run security checks on websites and downloaded files option.

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