Summary
This article explains the rules for using wildcards when creating exclusions using Antivirus for Qlik products.
Using wildcards when creating exclusions
Wildcards (?, *, **) are helpful in creating exclusions, but certain rules apply. See the examples below.
- The question mark (?) wildcard is used to represent a single character in the exact position where it is placed in the path or file name.
- The asterisk (*) wildcard is used to represent one or more characters, and does not cross a folder boundary.
- The double asterisk (**) wildcard is used to represent one or more characters, and does cross folder boundaries.
- System Environmental Variables such as %SystemRoot% can be used in exclusions. User Environmental Variables such as %UserProfile% can't be used, because the Antivirus scan runs under the Windows Local System account.
To show the difference between the * and ** wildcards, C:\Users\Will* matches path names such as C:\Users\William, C:\Users\Willamina, and C:\Users\WillAnderson. It does not match any subfolder of those names. For example C:\Users\Will*\** matches the previous folders and all their subfolders.
