Creating a scan exclusion

A scan exclusion is a set of conditions that must be fulfilled so that Kaspersky Endpoint Security will not scan a particular object for viruses and other threats.

Scan exclusions make it possible to safely use legitimate software that can be exploited by criminals to damage the computer or user data. Although they do not have any malicious functions, such applications can be exploited by intruders. For details on legitimate software that could be used by criminals to harm the computer or personal data of a user, please refer to the Kaspersky IT Encyclopedia website.

Such applications may be blocked by Kaspersky Endpoint Security. To prevent them from being blocked, you can configure scan exclusions for the applications in use. To do so, add the name or name mask that is listed in the Kaspersky IT Encyclopedia to the trusted zone. For example, you often use the Radmin application for remote administration of computers. Kaspersky Endpoint Security regards this activity as suspicious and may block it. To prevent the application from being blocked, create a scan exclusion with the name or name mask that is listed in the Kaspersky IT Encyclopedia.

If an application that collects information and sends it to be processed is installed on your computer, Kaspersky Endpoint Security may classify this application as malware. To avoid this, you can exclude the application from scanning by configuring Kaspersky Endpoint Security as described in this document.

Scan exclusions can be used by the following application components and tasks that are configured by the system administrator:

Kaspersky Endpoint Security does not scan an object if the drive or folder containing this object is included in the scan scope at the start of one of the scan tasks. However, the scan exclusion is not applied when a custom scan task is started for this particular object.

How to create a scan exclusion in the Administration Console (MMC)

Open the Kaspersky Security Center Administration Console.
In the Managed devices folder in the Administration Console tree, open the folder with the name of the administration group to which the relevant client computers belong.
In the workspace, select the Policies tab.
Select the necessary policy and double-click to open the policy properties.
In the policy window, select General settings → Exclusions.
In the Scan exclusions and trusted applications section, click the Settings button.
In the Trusted zone window, select the Scan exclusions tab.
This opens a window containing a list of exclusions.
Select the Merge values when inheriting check box if you want to create a consolidated list of exclusions for all computers in the company. The lists of exclusions in the parent and child policies will be merged. The lists will be merged provided that merging values when inheriting is enabled. Exclusions from the parent policy are displayed in child policies in a read-only view. Changing or deleting exclusions of the parent policy is not possible.
Select the Allow use of local exclusions check box if you want to enable the user to create a local list of exclusions. This way, a user can create their own local list of exclusions in addition to the general list of exclusions generated in the policy. An administrator can use Kaspersky Security Center to view, add, edit, or delete list items in the computer properties.
If the check box is cleared, the user can access only the general list of exclusions generated in the policy. If a local list was generated, after this functionality is disabled Kaspersky Endpoint Security continues excluding the listed files from scans.
Click the Add button.
To exclude a file or folder from scanning:
1. In the Properties section, select the File or folder check box.
2. Click the select file or folder link in the Scan exclusion description section to open the Name of file or folder window.
3. Enter the file or folder name or the mask of the file or folder name, or select the file or folder in the folder tree by clicking Browse.
  Use masks:
  - The * (asterisk) character, which takes the place of any set of characters, except the \ and / characters (delimiters of the names of files and folders in paths to files and folders). For example, the mask C:\*\*.txt will include all paths to files with the TXT extension located in folders on the C: drive, but not in subfolders.
  - Two consecutive * characters take the place of any set of characters (including an empty set) in the file or folder name, including the \ and / characters (delimiters of the names of files and folders in paths to files and folders). For example, the mask C:\Folder\**\*.txt will include all paths to files with the TXT extension located in the folder named Folder and its subfolders. The mask must include at least one nesting level. The mask C:\**\*.txt is not a valid mask.
  - The ? (question mark) character, which takes the place of any single character, except the \ and / characters (delimiters of the names of files and folders in paths to files and folders). For example, the mask C:\Folder\???.txt will include paths to all files residing in the folder named Folder that have the TXT extension and a name consisting of three characters.
4. In the Name of file or folder window, click OK.
  A link to the added file or folder appears in the Scan exclusion description section of the Scan exclusion window.
To exclude objects with a specific name from scanning:
1. In the Properties section, select the Object name check box.
2. Click the enter object name link in the Scan exclusion description section to open the Object name window.
3. Enter the name of the object type according to the classification of the Kaspersky Encyclopedia (for example, Email-Worm, Rootkit or RemoteAdmin).
  You can use masks with the ? character (replaces any single character) and the * character (replaces any number of characters). For example, if the Client* mask is specified, Kaspersky Endpoint Security excludes Client-IRC, Client-P2P and Client-SMTP objects from scans.
4. Click OK in the Object name window.
  A link to the added object name appears in the Scan exclusion description section of the Scan exclusion window.
If you want to exclude an individual file from scans:
1. In the Properties section, select the Object hash check box.
2. Click the object hash entry link to open the Object hash window.
3. Enter the file hash or select the file by clicking the Browse button.
  If the file is modified, the file hash will also be modified. If this happens, the modified file will not be added to exclusions.
4. Click OK in the Object hash window.
  A link to the added object appears in the Scan exclusion description block of the Scan exclusion window.
If necessary, in the Comment field, enter a brief comment on the scan exclusion that you are creating.
Specify the Kaspersky Endpoint Security components that should use the scan exclusion:
1. Click the any link in the Scan exclusion description section to activate the select components link.
2. Click the select components link to open the Protection components window.
3. Select the check boxes opposite the components to which the scan exclusion must be applied.
4. In the Protection components window, click OK.
If the components are specified in the settings of the scan exclusion, this exclusion is applied only during scanning by these components of Kaspersky Endpoint Security.

If the components are not specified in the settings of the scan exclusion, this exclusion is applied during scanning by all components of Kaspersky Endpoint Security.
You can use the check box to stop an exclusion at any time.
Save your changes.
