Scan Exceptions

If the scan exclusions are specified, a server admin will not perform a scan for the folders or files specified for scan exclusions when running a PC scan for agent computers. Allowed malicious codes or potentially malicious programs registered in the list for scan exclusions will not be scanned. If files, which do not have any potential risk of infection, are registered in the list for scan exclusions, the total scan duration can be reduced. You can register scan exception in the following way.

Note Note

When the option for Apply the scan exclusion list configured in the server is enabled in the scan exclusion settings, the scan exclusions can be specified. If Agent Settings are maintained, the server settings will not be applied.

To register scan exception:

Log in to the admin console.
Click Policy.
Click Add to move to Anti-Malware Policy > V3 Net.
Click PC Security > Scan Exclusions.
Enable or disable the policy configured in the server.

Maintain the agent settings: Applies the scan exceptions as a user-defined for agents.
Override and apply the server settings: Applies the scan exceptions defined by admin, regardless of the agent scan exception settings.

Select the Do not scan the items below checkbox.

Click Add to specify a scan exclusion. The scan exceptions can be a folder, a file or an extension. Scan exclusion can be added up to 50.

Folder: Adds a folder for a scan exception.
Path: Specifies a path for the selected folder. You can select the absolute path, Windows Program Files folders and Windows folders for the path.

Folder Name: Enter a folder name for a scan exception. The folder name must be in a format of 'Drive Name:\Folder Name’ or ‘Environment Variables\\Folder Name’. (ex: C:\Temp\FolderName, %TEMP%\FolderName)

File: Adds a file for a scan exception.
File Name: Enter a file name for a scan exception. The file name must be in a format of 'Drive Name:\Folder Name’ or ‘Environment Variables\\Folder Name\File name’. (ex: C:\Temp\FolderName\abc.txt, %TEMP%\FolderName\abc.txt)
Extension: Adds an extension for a scan exception. The extensions can be added up to 260 characters. (Alphabets only)

Note Note

If more than two extensions are added, separate them with a slash (/). For example, bmp/gif/txt.

Note Note

\ : * ? " . Characters such as < > | cannot be used for the extension. The executable files such as exe, dll or ocx cannot be entered for the scan exclusion.

Select the Do not scan the system restore folder checkbox.

Do not scan the system restore folder If Do not scan the system restore folder is selected, the system restore folder will not be scanned. The system restore folder allows tracking changes, which can damage a PC for the Windows to restore the system. As the system restore folder only allows the Windows to create the folder and to save the required file, the infected files found in the restore folder cannot be repaired as an anti-malware program does not have the write permission. The reason why a malicious code is found in the system restore folder is the Windows backs up the infected files whenever the files in the system restore folder is backed up. And therefore, if a malicious code is found in the system restore folder, the infected file cannot be repaired. If the system is restored using an infected file saved in the system restore folder, the system will be restored to be infected. When restoring the system, a user should make sure whether the file is infected or not. The system restore folder for Windows XP and Windows 7 is located in the Windows installation drive: :\WINDOWS\system32\Restore.

Click Add to add malware exclusions. You must enter the name of the malware alias as defined by V3.

Caution

Register a malicious code for scan exception as the excluded malicious will never be scanned. Use this feature only if necessary.

Click OK then Save.
