DTAM050 - McAfee VirusScan On-Demand scan must be configured so there are no exclusions from the scan unless exclusions have been documented with, and approved by, the ISSO/ISSM/DAA.
When scanning for malware, excluding specific files will increase the risk of a malware-infected file going undetected. By configuring antivirus software without any exclusions, the scanner has a higher success rate at detecting and eradicating malware.
Access the local VirusScan console by clicking Start->All Programs->McAfee->VirusScan Console. In the console window, under Task, with the assistance of the System Administrator, identify the weekly on-demand client scan task. Right-click on the Task and select Properties. Under the Exclusions tab, locate the 'What not to scan:' label, remove any items. Click OK to Save.
