Data Loss Prevention

To protect content of important folders from being changed by malicious software, use the Data Loss Prevention feature. With this feature enabled, you can view and add files to a protected folder, however, any modification or removal of files from this folder is blocked. To allow access to a folder for applications, add necessary applications to exclusions. You can also restore previously saved copies.

Protected folders

For each folder, you can configure application access parameters. You can view and copy the protected folder. You can also create new elements in this folder. When an application attempts to access the folder, a notification on access blocking will be displayed.

If you add a folder to the list of protected folders, a default rule is applied to it. Thus, any modification and removal of the folder content is restricted for all applications, except those from the list of trusted applications. To view this list, visit the website The list contains the most popular applications, for example, some Microsoft and Adobe applications. System processes, such as explorer.exe, are not included into the list of trusted applications as they can be used by malicious objects to attack the system.


It is restricted to add system folders to the list of protected ones. This may lead to critical system operation errors.


Data Loss Prevention applies only to local files and folders (physically located on your device) within the same operating system on which the protection is configured. If you have several operating systems on the same computer, you should configure Data Loss Prevention separately on each system. Protection of network files and folders is not possible.
