Rootkit Guru: AntiVirus Makes Me Do It http://www.emailbattles.com/archive/battles/security_aacejifdhf_ic/ "For the paid versions of Hacker Defender, the code of the public version is scrambled and changed to avoid antivirus detection. Tests for eight antivirus products (Avast!, AVG, Kaspersky, McAfee, NOD32, Norton, Panda, PC-cillin) with the newest upgrades, are always made before the customer receives the final product. The code is always unique for each customer, which means that detection of one customer's product should not affect other customer's products. " "It is curious that Hacker Defender's antidetection was implemented months ago and hasn't changed (except some minor bugfixes) since then. In spite of this fact, no security product is able to beat it today."
