In the Actions column, select "Edit Assignment". Locate the "Task to Schedule:" label. Verify the Product is "VirusScan Enterprise 8.8.0" and the Task Type is "On Demand Scan". In the Task name column, select "View Selected Task". Under the Reports tab, locate the "Log file size:" label. Criteria: If the "Limit the size of log file" option is selected and the "Maximum log file size:" is at least 10MB, this is not a finding. Locally, on the client machine, use the Windows Explorer to navigate to the following folder: (This folder may be hidden.) %SystemDrive%\ProgramData\McAfee\Common Framework\Task (64-Bit) If folder(s) do not exist, an alternative method of validating is via the following registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\DesktopProtection\Tasks] and are referenced by a GUID for each task. Multiple .ini files will be stored in this folder, one for each task defined on the ePO server for this client. The name for each task is identified in the first section of the file under the [Task] section on the TaskName= "" line. Additionally, a TaskType= line is provided to describe the type of scan.

If the bLimitSize value is 1 and the uKilobytes value is 10240 (Decimal) or more, this is not a finding.
