Antivirus Software Quiz

Antivirus software is designed to detect, prevent, and remove malicious software, such as viruses and malware, from computers. Its primary function is to safeguard the system's integrity and user data by scanning for threats and providing real-time protection against potential attacks. This helps maintain the overall security and performance of the device.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
