How is this different from any other anti-virus/anti-malware software?

While traditional anti-virus software maintains an ever-changing inventory of malware signature code to look for, Armored Client provides protection, even if keylogging or screen capture malware is on the device. The effectiveness of Armored Client is not dependent on the currency of a signature code list; it does not need to detect and respond to threats, the protection is designed to operate at the kernel level, the lowest level, preventing circumvention.
