Malicious software is commonly known as ____________.

  • Badware
  • Malware
  • Maliciousware
  • Illegalware
Correct Answer: B. Malware

Detailed Explanation

Malware is the general term used for malicious software that is created to harm, disrupt, damage, or gain unauthorized access to computer systems, networks, or data. The word "malware" is formed by combining the words "malicious" and "software." Therefore, Option B (Malware) is the correct answer.


Malware is designed with harmful intentions and can affect computers, smartphones, servers, and other digital devices. Once installed, it may steal sensitive information, corrupt files, slow down system performance, monitor user activities, or even lock data until a ransom is paid. Common types of malware include viruses, worms, Trojan horses, ransomware, spyware, adware, and rootkits. Each type has a different method of infecting devices and causing damage.


Malware usually spreads through infected email attachments, malicious websites, pirated software, fake downloads, removable storage devices, and phishing attacks. Users can reduce the risk of malware infections by installing trusted antivirus software, keeping the operating system updated, avoiding suspicious links, and downloading software only from reliable sources.


Key Point:



  • Malware: Software intentionally designed to damage or exploit computer systems. ✅

  • Common Types: Virus, Worm, Trojan Horse, Spyware, Ransomware, Adware, and Rootkit.

  • Common Sources: Phishing emails, infected downloads, fake websites, and USB devices.

  • Protection: Use antivirus software, install security updates, and avoid untrusted downloads.


Exam Tip: Remember this simple rule:



  • Malicious Software = Malware

  • Virus is only one type of malware, not the general term.
