A polymorphic virus not only replicates itself by creating multiple files of itself, but it also changes it's digital signature every time it replicates.

What type of virus mutates more easily?

Polymorphic and metamorphic viruses mutate more easily. Polymorphic viruses change their code or encryption pattern each time they infect a system, making them harder for antivirus software to detect. Metamorphic viruses go a step further by rewriting their entire code while keeping the same harmful function, which allows them to bypass traditional signature-based detection. Because of their ability to constantly change, these types of viruses are considered highly adaptable and more difficult to remove.
