If I were you, I would disable the notification, not the IP Blocker itself. You can do this by unticking the box next to "Show tooltip balloon" in the protection tab. I always leave the notifactions off and expect it to do its thing. While using Skype or other chat clients, it will block some IPs but not most (meaning the program works fine while not potentially exposing you to malware), and when using a web browsers it will regularly block IPs of ads that may be potentially dangerous. Unless you regularly visit free porn sites or something like that, the IP blocker will rarely prevent you from doing anything, but the notifications are annoying.
