I've been happily running FD-ISR 1.10 Build 173 together with NOD32 2.7 and Outpost 4. Thought I'd give BufferZone a try and the install went well and I clicked reboot to finish the BufferZone installation. My computer booted as normal until it got just past the WINXp screen with the running progress bar. As you now the screen goes blank briefly and one normally sees the blue "logging in" screen. At the blank screen phase the computer rebooted again and again and again. I tried booting from a complete shutdown and still got the endless loop of rebooting but never to a desktop. It struck me that FD-ISR changes the MBR and that perhaps BufferZone wasn't keen on this. FD-ISR worked fine and I booted my secondary snapshot and all is well. Is anyone successfully running FD-ISR with BufferZone or with Green Bordr for that matter? I knowI have enabled all the Threatsense options etc. in NOD and wonder if it is treating BufferZone is a malicious program. I would think though that the interference is too early in the boot process for NOD to be the culprit. Thanks for any comments.
