We would like to modify our VSE Full Scan settings using the registry. We do not want to use EPO since we would like users to be able to modify these settings. Is there any documentation on modifying the Full Scan settings with the registry?
I don't know of any documentation, but here are some pointers.
You'd have to disable Access Protection (if enabled) [the rule protect McAfee Files and Settings]
Configure up a scan task on one computer the way you want it to be, right click, copy, and then paste into Notepad. This will give you the various registry settings.
Scan tasks are stored under HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\DesktopProtection\Tasks in the registry. Have a look at szTaskName to find the task name. I believe the Full Scan task has the same registry CLSID on all machines (but aren't 100% sure).
