I just installed Zone Alarm Security Suite as trial installation. No problems on install - except I had to uninstall Trend Micro IS2005 due to an IS2005 auto-start process that is not menu-controllable. Good menu, good Help, no conflicts with either TrojanHunter Guard, MS AntiSpyware Beta or Spy Sweeper. Observation: - All in/out spam filtering is enabled in ZA menus. - Process Explorer shows process mantispm.exe (spam filter) as disabled. - Task Manager confirms this process not running. Question: Is this process disabled simply because this is trial install? Thanks for your help!
