Self-replicate across email

Display warning messages

15. Which statement about viruses is correct?

Viruses can spread without any host file

Viruses require a host file to attach to and replicate

Viruses propagate independently across networks

Viruses only infect executable files

16. Ransomware typically enters a system through which method?

Automatic network propagation

Phishing emails, malicious downloads, or exploit kits

Bootable USB drives only

File sharing protocols exclusively

Virus

Worm

Trojan

Logic bomb

Worm

Trojan

Spyware

19. A trojan horse is best described as:

Self-replicating code that spreads via email

A program that encrypts system files

Code injected into boot sector during startup

20. What is the primary characteristic of ransomware?

It replicates across network shares

It encrypts files and demands payment for decryption

It creates backdoors for remote access

It copies itself to the boot sector
