Performance exclusions

This feature allows 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.


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 exlink for more information.


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 file name.


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


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 particular file located in the exact path


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)


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 format:













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