Hi folks! I just installed RegDefend and the very first alert I received was to Allow or Block TCP/IP Parameters for System. I chose allow, assumed if I blocked it the computer wouldn't work. Hope this is correct. One more question...... how do I open the Suite? When I right click on the system tray icon it says "I won't get alerts basically". When I click on the desktop icon it says it's already running. I just wanted to open it and look around. Using Tony Kliens ruleset. XP Home w/SP2. Thanks in advance for any help!
