Performance exclusions

This feature enables you to exclude files and folders from scanning. Performance exclusions are useful to exclude file-level scanning of mission critical applications or when scanning causes abnormal system behavior or decreases performance.

We recommend creating performance exclusions only when necessary to ensure that all objects are scanned for threats. However, there are situations when you may need to exclude an object, such as large database entries that would slow your system during a scan or software that conflicts with the scan.

Path

Excludes specific path (file or directory) for this computer. Do not use wildcards – asterisk (*) in the middle of a path. See the following Knowledgebase article for more information.

Note

To exclude folder contents, do not forget to add the asterisk (*) at the end of the path (C:\Tools\*).

C:\Tools will not be excluded, because from the scanner's perspective, Tools can also be a filename.

Comment

Add an optional Comment to easily recognize the exclusion in the future.

Example

Path exclusions using an asterisk:

C:\Tools\* – path must end with the backslash (\) and asterisk (*) to indicate that it is a folder and all folder content (files and subfolders) will be excluded

C:\Tools\*.* – the same behavior as C:\Tools\* which means, it works recursively

C:\Tools\*.dat – will exclude dat files in the Tools folder

C:\Tools\sg.dat – will exclude this specific file located in the exact path

Example

To exclude all files in a folder, type the path to the folder and use the mask *.*. To exclude doc files only, use the mask *.doc.

If the name of an executable file has a certain number of characters (and characters vary) and you only know the first one for certain (say “D”), use the following format:

D????.exe (question marks replace the missing / unknown characters)

Example

Use system variables like %PROGRAMFILES% to define scan exclusions.

To exclude the Program Files folder using this system variable, use the path %PROGRAMFILES%\ (make sure to add the backslash at the end of path when adding to exclusions)

To exclude all files in a %HOMEDRIVE% subdirectory, use the path %HOMEDRIVE%\Excluded_Directory\*.*

The following variables can be used in the path exclusion form:

%ALLUSERSPROFILE%

%COMMONPROGRAMFILES%

%COMMONPROGRAMFILES(X86)%

%COMSPEC%

%HOMEDRIVE%

%HOMEPATH%

%PROGRAMFILES%

%PROGRAMFILES(X86)%

%SystemDrive%

%SystemRoot%

%WINDIR%

%PUBLIC%

User-specific system variables (like %TEMP% or %USERPROFILE%) or environment variables (like %PATH%) are not supported.
