I use Online Armor Premium version 126.96.36.1997 with Windows XP Pro Service Pack 3. I shut my system down overnight. Each morning when I start it up, Online Armor hangs it up. I have disabled Online Armor at start-up and don't have any problems with it. I start it manually and it works fine. Or, after my system has been on for a while, I can reboot and it loads fine. Why would it make a difference when my system is cold. It's not a big problem but it has me puzzled. Can anyone understand what the difference is?
