Viruses
What are 10 types of virus classifications?
Boot sector Marco Program Multipartite Encrypted Polymorphic Metamorphic Stealth Armored Hoax

Boot sector
A virus embedded into a document and is executed when the document is opened by the user.
Macro
Viruses that infect an executable or application.
Program
Viruses that combine boot and program viruses to first attach itself to the boot sector and system files before attacking other files on the computer.
Multipartite
Viruses that use a cypher to encrypt the contents of itself to avoid detection.
Encrypted
An advanced version of an encrypted virus that changes itself every time it is executed by altering the decryption module to avoid detection.
Polymorphic
A virus that is able to rewrite itself entirely before it attempts to infect a file. An advanced version of a polymorphic virus.
Metamorphic
A category of viruses that use various techniques to avoid detection. Examples are encrypted, polymorphic and metamorphic.
Stealth
Viruses that have a layer of protection to confuse a program or person analyzing it.
Armored
A virus used to trick a user into infecting their own machine.
Hoax
Malicious software like a virus, but is able to replicate itself and spread without user consent or interaction.

Trojan Horse
Provides the attacker with remote control of the victim computer and is the most commonly used type of trojan.

Is commonly used by rootkits to maintain persistent control.
DLL Injection
A type of rootkit that relies on compromising the kernel-mode device drivers that operate at a privileged or system level. Acts as a shim that is placed between two components to intercept called and redirect them.
