Partial content blocking

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

Blocked 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 isn't specifically malicious in the classical sense, but it takes up a lot of memory, consumes the battery, and heats up the components of the smartphone.

To prevent miners from using your smartphone resources to earn money, Yandex Browser blocks the downloading of mining scripts from websites. Scripts can be blocked even if they're yet unknown to the browser. The browser analyzes the CPU load generated by sites and uses this data to block previously unknown mining scripts.

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