    Preface Anti-virus protection as information security “The world changed [on March 26, 1999]—does anyone doubt that? The world is different. Melissa proved that ... and we are very fortunate ... the world could have gone very close to meltdown.” —Padgett Peterson, Chief Info Security Architect, Lockheed Martin Corporation, on the 1999 “Melissa”...

    The scan engine, meanwhile, combines the best features of technologies that McAfee and Dr Solomon researchers developed independently for more than a decade.
  • Page 24 This meant that the simple pattern-matching method that earlier scan engine incarnations used to find many viruses simply no longer worked, since no constant sequence of bytes existed to detect. To respond to this threat, McAfee researchers developed the PolyScan Decryption Engine, which locates and analyzes the algorithm that these types of viruses use to encrypt and decrypt themselves.
