Sandbox

 

Sandbox is a virtualization tool in Avast Business Antivirus that allows you to browse the web or run applications in a virtual, safe environment that is completely isolated from the rest of your PC's system. This feature is useful when you want to run suspicious or untrusted applications without risk.

When you run an application in Sandbox, all necessary files are always copied to Sandbox storage where they can be modified as needed without affecting the original files. Any new files created during virtualization are also saved to Sandbox storage. Sandbox storage is a file space completely isolated from the rest of your system and other Sandboxes. By default, Sandbox storage is created in the same drive as the original file.

Sandbox is not available for macOS devices.

Configuring Sandbox Settings

To access Sandbox settings:

1. Open the Policies page
2. Click the desired policy to open its settings
3. Select the OS (Windows Workstation or Windows Server), then go to the Active Protection tab
4. Click Customize next to Sandbox

The available configuration options will be split into six tabs:

• Sandbox storage
• Web browsers
• Virtualized processes
• Privacy
• Exclusions
• Internet access

Sandbox Storage

Within this tab, you can specify where Sandbox storage is created, choosing either the same drive as the modified file or a different location.

Web Browsers

The settings available here are designed to improve the sandboxed browser's performance. You can:

• Choose whether trusted downloaded files will be saved outside of Sandbox
• Exclude certain browser features from virtualization so that they are not deleted after closing Sandbox
• Cache virtualized files for web browsers only, and delete all other virtualized files

Exclusions can be applied to browser bookmarks, history, and/or cookies. If you, for example, exclude browsing history from virtualization, it will remain available when the browser is opened outside of Sandbox.

If you enable maintenance (caching only browser files), you will have the additional option to schedule automatic Sandbox storage cleanup.

Virtualized Processes

In this section, you can set up a list of applications and/or folders that will automatically run in Sandbox.

Privacy

Within this tab, you can specify which locations can or cannot be accessed by virtualized applications. You can select from the listed preset locations or specify the locations manually. This provides an additional layer of protection, as the selected locations will be completely invisible to virtualized apps.

Exclusions

Configure the list of locations that are not virtualized by entering the exact file location path to be excluded. These exclusions will only apply when Sandbox is used to virtualize potentially infected files, and will ensure the specified locations are not brought into the virtualized environment.

For more information on standard and component-specific exclusions, see Configuring Antivirus Exclusions.

Internet Access

Here, you can specify whether to allow all/specific virtualized apps to access the internet or block internet access for all virtualized applications.

Overriding Policy Settings

Via the Components tab of a device, you can override its policy configuration for Sandbox by setting the Customize component installation settings toggle to ON and then clicking install/uninstall next to the component.
