Many of the protection shields and other components included in Avast Business products, as well as the main Antivirus itself, enable you to configure exclusions or block specific paths. Wildcards help when you do not know the exact file path or file names of files you want to include or exclude, or when you want to indicate multiple files in a single path. Also, wildcards should be used instead of user/system variables (e.g. %userprofile%, %systemroot%), as these variables are not supported anywhere except in Firewall settings and Ransomware Shield.
Note that not all file paths allow the use of wildcards.
Replaces a single character
Replaces zero or more characters
Under certain circumstances, you will not get the expected result without using wildcards. For example:
- To exclude all HTML files, type
*.htm*into the text box. Typing
.htminto the text box will not include any files because no full file name is represented.
- To exclude a folder and its sub-folders, add
\*to the end of the folder name, for instance
- To exclude all files labeled in a certain way on any of your hard drives, include
?:\in front of the path, for instance
File/Folder Exclusion Examples
Normal file path:
Executables regardless of file path: *\example.exe
A folder and all contents in any location:
Batch Script Files: You may need to also add exclusions for command-line files executed within batch script files detected as a threat by Avast.
Folder exceptions must include the trailing backslash (\) and asterisk (*) to correctly exclude the whole folder and subfolders; otherwise, the exception will be ineffective.
Behavior Shield and Hardened Mode do not support inserting wildcards at the beginning or in the middle of a file path (for example,
C:\users\*\application.exe). However, you can still use a wildcard at the end of the path (for instance,
URL Exclusion Examples
To add, for example, https://www.avast.com/ as a URL exclusion, you can use any of the following:
- dns://*.avast.com* (to exclude DNS server in the Real Site component)
URL/DNS exceptions can contain wildcards in the domain, but only the whole domain will be added.
