AntispyKnight is renegade security tool which gets distributed by Trojans. The main goal of AntispyKnight is to extort money from people that care about their computer security. Also known as Antispy Knight, this malware application is advertised as anti-spyware, very aggressively and in very annoying ways. AntispyKnight slows down the infected computer and makes it impossible to browse the web. Furthermore, Antispyknight.info becomes the only website that can be accessed. This malware loads a variety of pop-up messages as well. Both the website and the pop-ups urge the user to purchase a full version of Antispy Knight. This application is pure malware and it is a part of scam. AntispyKnight is a destructive program that masquerades as a benign application. Unlike most computer viruses, Trojan horses do not tend to replicate or duplicate themselves but they have proven to be just as destructive as most. One of the most insidious types of Trojan horse is a program that claims to be able to rid a user’s computer of viruses but instead introduces viruses onto the computer. AntispyKnight is particularly damaging to a computer system, once it has fully embedded itself within the PC’s system, therefore it is given a high priority security risk status by many computer analysts. The risks which may affect an infected PC’s system functions include: the opening of illicit network connections, the use of polymorphic tactics to self-mutate, the disabling of already installed security software, modification of system files, and not forgetting the installation of additional malware. Furthermore, these security risks may also collect and transmit personally identifiable information (PII) without the user’s consent thus severely degrading the performance and stability of the computer. The best way to deal with the threat of AntispyKnight is to simply remove it from the affected PC system.
