I think i've achieved a master protection scheme by using just these "4" security apps on a single workstation. They include DEEP FREEZE + Anti-Executable + HIPS= EQS rounding these out with famous SandboxIE because they ALL are 100% compatible together . To add the icing to the cake with such a safe iron wall i propose to include SuRun to keep LUA as the cap for them all to repel any potential for forced admin rights elevation? Is this in your experience and opinion really an intelliigent move as well as practical? Do you see any reason why this combination wouldn't add for all sensible & safe purposes the very final log chain to securing an XP system? I can always abort DF + AE just long enough to add safe apps or even insert them to AE's whiltelist while DF is suspended temporarily? Thanks for making all of us more prepared than common basic apps.
