How does a rootkit pose a cybersecurity threat? More than one answer may be correct.

A range of malicious actions is possible because the invader has the same access as the computer's owner or user.

A rootkit invasion usually can be fixed by restarting the computer.

The malware can spread to access and control a network without the host computer user's awareness.

Installed on a computer's operating system, a rootkit bypasses security functions.
