I posted here this thread because many people use ProcessGuard with Prevx together. I'm interested in file protection of Prevx. Some settings of Prevx are similar to ProcessGuard and I think it may be a good idea changing them to avoid overlay - Buffer OverFlow - Win XP Heap - Buffer OverFlow - Win XP Stack - Windows Memory - Phisical Memory Overwrite - Prevx misuse (registry - execution) shoul be turn off? Any suggestions about these or other settings of Prevx? Thanks in advance for your replies.
