This topic describes syntax guidelines to follow when you create an exclusion.

Command lines can include leading or trailing whitespaces, but their number and location must be exact to correctly identify the process.

Paths cannot end with a period or whitespace, and Windows Environment variables such as %System% are not allowed.

The following path entries are accepted:

Type Example
NT device paths \\?\globalroot\device\harddiskvolume1\example.exe
Volume GUID names \\?\Volume{34b06610-97bc-4d11-b040-tc8a7bff1f41}\
Paths without pathname separators (backslash) or extensions system, registry
Paths starting with system-wide DOS drive letters c:\test.exe, d:\example.exe
Alternate Data Stream (ADS) names c:\example.exe:test.txt
UNC device paths \\server\share\directory\file.exe
