Since ProcessGuard will apparently not progress any further I am thinking of switching over to AppDefend as I already am using RegDefend. How easy is AppDefend to use. Is there any on-line instructions for installing and configuring? Is there a learning mode? If not how do you load all of the Windows XP stuff. I also have WormGuard. Does AppDefend have any scripts/worm protection? What are the major differences between AppDefend and ProcessGuard. Will it have any compatibility problems with KAV, Outpost firewall, BoClean or WinPatrol? Thanks for any answers you can provide.
