What is malware?

Malware refers specifically to malicious software that is created with the intent to harm, exploit, or compromise a computer system or network. This type of software can take various forms, including viruses, worms, Trojans, ransomware, spyware, and adware, each designed to impact a system negatively in different ways. The primary characteristic of malware is its malicious intent, which is to disrupt normal operations, steal sensitive information, or gain unauthorized access to networks or devices.

Understanding the definition of malware is crucial for anyone studying cybersecurity, as it lays the foundation for recognizing potential threats and implementing strategies to protect systems from such attacks. The term itself is a portmanteau of "malicious" and "software," reflecting its harmful nature.

The other choices provided do not align with this definition. Enhancing computer performance, web applications for cloud storage, and encryption methods do not inherently involve malicious intent or impact system security negatively, which distinguishes them clearly from the concept of malware.
