2. Which of the following is NOT a type of malware that antivirus software detects?

Explanation

Spam emails are not classified as malware; they are unsolicited messages often used for advertising or phishing. While antivirus software may filter spam, its primary function is to detect and remove malicious software like viruses, worms, and Trojans, which actively harm systems. Spam emails typically do not contain harmful code themselves.

Submit

3. What does 'real-time scanning' mean in antivirus software?

Explanation

Real-time scanning in antivirus software refers to the continuous monitoring of files and processes as they are accessed. This proactive approach ensures that any potential threats are detected and neutralized immediately, providing enhanced protection against malware and other security risks as users interact with their systems.

4. A ____ is a malicious program that tricks you into downloading it by pretending to be something safe.

Explanation

A Trojan is a type of malware that disguises itself as legitimate software to deceive users into downloading it. Once installed, it can perform harmful actions on the user's device, such as stealing data or giving unauthorized access to attackers, all while remaining hidden under the guise of a trustworthy application.

Submit

5. Why is it important to keep your antivirus software updated?

Explanation

Keeping antivirus software updated is crucial because new viruses and malware are constantly being developed. Regular updates ensure that the software can recognize and defend against these emerging threats, providing better protection for your computer and personal information. This proactive approach minimizes the risk of infections and security breaches.

Submit

6. True or False: Antivirus software can completely guarantee your computer will never get infected.

Explanation

Antivirus software significantly reduces the risk of infections by detecting and removing malware. However, it cannot provide a 100% guarantee due to constantly evolving threats, user behavior, and potential vulnerabilities in the system. New malware can emerge before antivirus updates can address them, making complete protection impossible.

Submit

7. What is a 'virus definition' in antivirus software?

Explanation

A virus definition in antivirus software refers to a database of known virus signatures. These signatures are unique patterns or characteristics of viruses that the software uses to detect and identify potential threats on a computer system, ensuring effective protection against malware.

Submit

8. A ____ is a self-replicating program that spreads from one computer to another without user action.

Explanation

A worm is a type of malicious software designed to replicate itself and spread across networks without requiring any user intervention. Unlike viruses, which attach themselves to files or programs, worms exploit vulnerabilities in systems to propagate, often causing significant damage by consuming bandwidth and resources.

Submit

9. Which action helps protect your computer from malware?

Explanation

Running regular antivirus scans helps detect and remove malware before it can cause harm to your computer. These scans identify malicious software that may be hidden, ensuring your system remains secure. Regular updates and scans enhance protection against evolving threats, making it a crucial practice for maintaining computer safety.

Submit

10. What does 'quarantine' mean when antivirus software detects a threat?

Explanation

Quarantine in antivirus software refers to the process of isolating a detected threat, such as a virus or malware, preventing it from executing or spreading. This allows users to safely examine or remove the infected file without risking damage to their system, ensuring ongoing protection while addressing the potential threat.

Submit

11. True or False: Free antivirus software provides the same protection as paid versions.

Explanation

Free antivirus software often lacks the comprehensive features and advanced protection mechanisms found in paid versions. While they may offer basic protection against common threats, paid options typically include real-time scanning, regular updates, customer support, and additional security features, making them more effective in safeguarding against a wider range of cyber threats.

Submit

12. A ____ is a type of malware that secretly collects your personal information without your knowledge.

Explanation

Spyware is a malicious software designed to infiltrate devices and gather sensitive information, such as passwords, credit card details, and browsing habits, without the user's consent. It operates discreetly in the background, often leading to privacy violations and potential identity theft, making it a significant threat in the realm of cybersecurity.

Submit

13. What should you do if antivirus software finds a virus on your computer?

Submit

14. Which of these is a sign that your computer might have malware?
