Answer 1

The correct answer is Polymorphic virus.

Key Points

A polymorphic virus is a complicated computer virus that affects data types and functions.
Polymorphic viruses are complex file infectors that can create modified versions of themselves to avoid detection yet retain the same basic routines after every infection.
Upon infection, the polymorphic virus duplicates itself by creating usable, albeit slightly modified, copies of itself.
To vary their physical file makeup during each infection, polymorphic viruses encrypt their codes and use different encryption keys every time.
It is a self-encrypted virus designed to avoid detection by a scanner.
