“Kuzzle”通过篡改电脑系统中的主引导记录（MBR）和卷引导记录（VBR），在不修复主引导区情况下，用户即使重装系统也无法根除。火绒工程师表示，近几年，通过MBR、VBR感染进行深度技术对抗的病毒和流氓软件逐渐增多，流氓软件已完全病毒化，越来越多的使用病毒技术，其手段强劲、性质恶劣，对用户的危害甚至超过传统病毒。("Kuzzle" can tamper with the main boot record (MBR) and volume boot record (VBR) in the computer system, and even if the main boot area is not repaired, the user can not eradicate the system even though it is reinstalled. Tinder engineers said that in recent years, through MBR, VBR infection depth technology against virus and malware gradually increased, rogue software has been completely virus, using virus technology more and more, which means strong, harsh nature, harm to the user even more than the traditional virus.)
