VM (Virtual Machine): a software-based emulation
VM (Virtual Machine): a software-based emulation of a physical computer system that runs an operating system and applications
hypervisor: a layer of software that enables virtualization by controlling access between virtual machines and the host hardware
type 1 hypervisor: a hypervisor that runs directly on the host hardware, as opposed to running on top of an operating system
Polymorphic viruses: These are viruses that have the ability to change their code to avoid detection by antivirus software. They do this by modifying their code each time they infect a new system, while still retaining their functionality.
RIPEMD160: This is a cryptographic hash function that produces a 160-bit hash value. It is considered to be secure and collision-free, meaning it is difficult to find two inputs that produce the same hash output.
MD5: This is a widely used cryptographic hash function that produces a 128-bit fixed-length hash value. However, it has been found to have flaws that allow collisions to be produced in a reasonable amount of time.
MD6: This is a cryptographic hash function that was designed to replace MD5, but was withdrawn due to flaws. It was not used for very long.
SHA1: This is a cryptographic hash function that produces a 160-bit hash value. It was found to have weak collision avoidance, but is still commonly used.
