Mini-filter AutoProtect uses Microsoft’s own filter manager to hook file system activity. Mini-filter AutoProtect registers with filter manager, which passes the file information to AutoProtect for scanning. For more information on mini-filters see http://msdn.microsoft.com/en-us/library/ms793580.aspx.
Legacy mode AutoProtect uses Symantec’s SymEvent driver to hook file system activity. SymEvent passes the file information to AutoProtect for scanning. Legacy AutoProtect originated with SAV’s real time file scanning. It has the same functionality as mini-filter AutoProtect.
It is assumed that eventually Microsoft will stop allowing legacy file system filter drivers like Symevent to load, which is why a mini-filter version of Autoprotect was created
