Only create exclusions when it is absolutely necessary
To ensure that all objects are scanned, we recommend only creating exclusions when it is absolutely necessary. Situations where you may need to exclude an object might include scanning large database entries that would slow your computer during a scan or software that conflicts with the scan.
Click Detection Engine, expand Exclusions and then click Edit next to Performance exclusions.
Click Add and click Browser (...).
Use the directory tree to browse for the file or folder you want to exclude, select it and then click OK.
Click OK → OK to save the exclusion.
Use wildcards to exclude a group of files. Use a question mark (?) to exclude a single character and an asterisk (*) to exclude a string of characters. We recommend that you do not use wildcards in the middle of a path. For more information about using wildcards, visit our Online Help topic.
To add an exclusion using a detection name or SHA1 file hash, use Detection Exclusions. Excluding by detection name or SHA1 file hash poses a high-security risk and is recommended only for advanced users.
