Access protection prevents unwanted changes to your computer by restricting access to specified ports, files, shares, registry keys, and registry values. It also protects McAfee processes by preventing users from stopping them. This protection is critical before and during outbreaks.
This feature uses predefined rules and categories and user-defined rules to specify which items can and cannot be accessed. Each rule can be configured to block and/or report access point violations when they occur. Predefined rules and categories are subject to content updates via the McAfee update sites.
