CrystalAEP (Crystal Anti-Exploit Protection) is designed to provide frontline protection against Internet-borne threats such as viruses and malware. Unlike the typical anti-virus program, Crystal does not attempt to recognise threats based on signatures, and does not require constant updating to protect against the latest threats. Crystal works instead by manipulating at-risk software while it runs to help form an environment which is hostile to Internet worms, malware and other types of malicious code.
