Title

McAfee VirusScan On-Access Default Processes Policies must be configured to scan all files. (Cat II impact)

Discussion

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.
