Protect: partial content blocking

Sometimes dangerous elements from infected resources (banners, scripts, or sidebars) or mining scripts can show up on otherwise safe sites. The Protect integrated security system is used in Yandex Browser to block these elements. The data on unsafe resources is taken from a special database compiled by Yandex and our partners.

Blocking dangerous elements

If the page in question contains elements from infected sites, Yandex Browser warns you. If you get to the page by clicking the Ignore this warning button, your browser will display the page but block the dangerous elements. The right part of the SmartBox will display the icon.

You cannot load the blocked content, because it presents a serious risk to your computer. Because the browser only downloads secure elements, the page may be formatted incorrectly.

Disable blocking

Attention. If you want to disable blocking dangerous content, 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 dangerous content blocking:

  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 the same algorithm to re-enable blocking of dangerous content.

Blocking mining scripts

Mining is often used for issuing cryptocurrencies, such as Bitcoin. The computer makes calculations and its owner is awarded a certain amount of cryptocurrency.

In the case of hidden mining, the miners use the resources of other people's computers and mobile devices to make the calculations. The mining code might be hidden in JavaScript on website pages. This code can't be called malicious in the classical sense, but it actively utilizes RAM, comsumes the battery and heats the computer components.

To prevent miners from earning money using your computer's resources, Yandex Browser blocks mining scripts from sites.

Note. The browser also blocks other hidden mining options, such as those that use extensions.

If you want to stop blocking mining scripts, disable ad filters in the browser.
