I was surprised to discover you can easily stop the "Norton Internet Security" service from the Services MMC or simply via a "net stop" command. Why does the tamper protection feature not prevent this? If I can do this so can a virus.
Kaspersky and NOD32 v4 both prevent their services from being stopped (Access Denied errors) so I was disappointed to discover this.
