Description
When scanning for malware, excluding specific file types will increase the risk of a malware-infected file going undetected. By configuring antivirus software to scan all file types, the scanner has a higher success rate at detecting and eradicating malware. The excluding of files, paths, and processes from being scanned expands the potential for malware to be allowed onto the information system. While it is recognized that some file types might need to be excluded for operational reasons and/or because there is protection afforded to those files through a different mechanism, allowing those exclusions should always be vetted, documented and approved before applying.
