What is malware?

Malware is defined as malicious software specifically designed to exploit, harm, or otherwise compromise the functionality of devices, networks, or data. This encompasses a wide range of harmful software types, including viruses, worms, trojans, ransomware, and spyware, all of which can cause significant damage or unauthorized access to systems.

The nature of malware is to perform undesired actions on the victim's device, often without their knowledge. This can include stealing sensitive information, corrupting files, or disrupting services. Understanding the malicious intent behind malware is crucial for implementing effective security measures to protect systems from such threats.

In contrast, software that improves system performance, anti-virus programs, and backup software serve beneficial purposes that are fundamental to maintaining and enhancing the integrity and functionality of a computer system. Therefore, recognizing malware as intentionally harmful software distinguishes it from applications that are designed to achieve positive outcomes.
