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 you want to visit contains elements from infected sites, Yandex Browser blocks them. The icon appears in the SmartBox.

If you want to load blocked content:

  1. Tap .
  2. In the Block ads on this site section, click Learn more.
  3. Click Unblock for this tab.

If blocked content is a serious threat to your computer, you will not be able to load it. In this case, there will be no Learn more link in the Block ads on this site section.

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. 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 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. Scripts can be blocked even if they are yet unknown to the browser. The browser analyzes the CPU load generated by sites and uses this data to block previously unknown mining scripts.

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.
