Final answer:
A worm is the most likely type of malware that is infecting other computers without user intervention.
Step-by-step explanation:
The type of malware that is most likely infecting other computers without any user intervention is a worm.
A worm is a type of malware that can spread across a network and infect other computers without the need for human interaction. Unlike viruses, worms do not require a host file or program to infect other systems. They are standalone programs that can self-replicate and spread autonomously.
Once a computer is infected with a worm, it can scan the network for other vulnerable systems and exploit security vulnerabilities to gain access and infect them. This can lead to a rapid spread of the malware throughout the corporate network.
