This is the standard McAfee Web Gateway PreConfig file.
It is restored onto a fresh MWG to create a well-populated starter policy for PoCs and demos in order to rapidly demonstrate features.
It is compatible with MWG version 188.8.131.52 and above.
Although there is no general harm I know of, this should not be used in production systems because it contains excessive features that may or may not be applicable to any particular needs.
McAfee/Intel Security makes no Guarantees as to its efficacy for any particular use.
If you need help with it, don't contact support.
