Mobile Yandex Browser checks downloaded files for viruses and blocks pages with malicious software.
Blocking dangerous pages
When you open a web page, Yandex Browser checks it against its database of infected sites. If the page is found in the database, it won't load. The screen will display a message and the icon will appear in the SmartBox. You can nevertheless choose to ignore the warning and visit a site with dangerous content.
Checking downloaded files for viruses
Downloaded files may contain malicious code. This is why the browser scans all archives and executable files that are downloaded both directly and in the background.
If a downloaded file contains a malicious program, the browser warns you and offers to delete the file.
