Protect: check downloading files

Attention! Yandex.Browser can protect you from malicious code downloads, but doesn't guarantee absolute protection from all modern threats to your computer. For more complete protection, use professional antivirus software in conjunction with Protect.

Downloading files scanned automatically

Files being downloaded may contain malicious code or programs you just don't want. Malicious software that gets onto your computer can negatively impact its performance and steal, damage, or delete your information. Unwanted programs can do things like display annoying ads, install hidden software, or open third-party pages in your browser. Therefore, the browser scans all archives and executable files (regardless of if they are downloaded openly or in the background).

Archives and executable files are checked when downloading starts. The browser flags certain file characteristics and sends them to be checked by the antivirus cloud on the Yandex server. Only the problematic part of the file is transferred to ensure that the security check goes as quickly as possible.

A file that is being checked can not be opened and its icon on the right side of SmartBox turns partially-transparent.

The browser blocks dangerous files that contain malware and warns you about suspicious files that install unwanted software.

Blocking dangerous files

If a downloading file contains a malicious program, the browser will block it. Infected files are marked with the icon. When you try to open this type of file, you'll see the following dialogue window:

The browser keeps files containing malware and adds the infected extension to the file name. The file cannot be launched in this form from the browser or using any other software. This means the infected file can no longer pose a threat, but an antivirus program installed on your computer might still consider it dangerous.

If you didn't immediately delete the infected file, you can do so later from your Downloads folder:

  1. Click the icon  Downloads.
  2. Click Delete under the file.

Suspicious file warning

Files that can install programs without your permission, show annoying ads, or automatically send you to third-party pages in your browser when opened are considered suspicious. The browser denotes these types of files with a icon when they are loading. If you attempt to open this type of file, the following dialogue window displays:

We do not recommend opening suspicious files because they may serve you unwanted advertising. If you want to open the file anyway:

  1. Click the icon  Downloads.
  2. Click Open under the file.

Disable protection

Attention! If you don't want files and sites to be checked, you need to completely disable your shield against malicious software and websites. We do not recommend this.

To disable malware protection

  1. Click the icon  Settings.

  2. In the lower part of the Settings page, click the Show advanced settings button.

  3. In the Privacy section, disable the Protect from malicious websites and software option.
  4. Restart the browser to apply the changes.
