First, keep in mind my answers to ZoneAlarm questions will be from years of experience with computers and security, not experience with ZoneAlarm. OK, then. [*:v27ig9bz]They are parts of the Windows subsystem. ZoneAlarm won't let you change them because that would cause problems. [*:v27ig9bz]That doesn't matter. It should, depending on your settings, ask you about them when they try to access the internet. [*:v27ig9bz]I don't know...it depends on your system. For the most part, anything that needs to get things from the Web (MS Word, IE, Firefox, Online Games, VirusScan and Firewall updates...) should be allowed.
