12. Question 12 of 30

    Common early symptoms of a malware infection on a computer can include:

    A Immediate and complete physical destruction of the hardware B Automatic improvement in overall system performance C Unusual slowdowns, crashes, and unexpected pop-ups D No symptoms at all, in literally every case
13. Question 13 of 30

    Keeping regular backups of important data is a recommended security practice primarily because it helps:

    A Guarantee that malware can never infect a system again B Protect against data loss from malware attacks such as ransomware C Permanently increase a computer's processing speed D Eliminate the need for any antivirus software
14. Question 14 of 30

    Macro viruses are a type of malware specifically embedded within:

    A Documents and spreadsheets that support macro scripting B Computer hardware firmware exclusively C Network router configurations exclusively D Physical USB cable connectors
15. Question 15 of 30

    A honeypot, used in cybersecurity research and defense, is best described as a:

    A Type of destructive malware used by hackers B Standard antivirus software feature C Physical lock used to secure server rooms D Decoy system designed to attract and study attackers' methods
16. Question 16 of 30

    A 'backdoor' in computer security refers to a:

    A Hidden method of bypassing normal authentication to gain unauthorized system access B Standard password reset procedure C Type of antivirus scanning technique D Firewall configuration setting
17. Question 17 of 30

    A 'drive-by download' refers to malware that is installed on a system:

    A Only after a user explicitly agrees to install new software B Only through physical access to the computer C Only via a direct phone call from the attacker D Automatically, simply by visiting a compromised or malicious website
18. Question 18 of 30

    Adware is a type of software that is primarily known for:

    A Encrypting files and demanding ransom B Secretly recording keystrokes C Displaying unwanted advertisements, often bundled with free software D Granting attackers remote control of a system
19. Question 19 of 30

    A Trojan horse, a type of malware, is named for its tendency to:

    A Replicate itself extremely rapidly across networks B Only target email servers specifically C Physically damage computer hardware instantly D Disguise itself as legitimate or useful software to trick users into installing it
20. Question 20 of 30

    A botnet refers to a network of:

    A Legitimate servers used for cloud storage B Compromised computers controlled remotely, often without their owners' knowledge C Antivirus programs working together D Secure, encrypted communication channels
21. Question 21 of 30

    Spyware is malicious software designed primarily to:

    A Display disruptive pop-up advertisements only B Secretly monitor and collect information about a user's activities C Permanently delete all files on a system D Physically damage a computer's hard drive
