What is the primary purpose of malware?

The primary purpose of malware is to interrupt computer operations and gain unauthorized access. Malware is designed specifically to infiltrate, damage, or disrupt computer systems and networks. Its various forms, such as viruses, worms, and Trojan horses, are crafted to exploit vulnerabilities and can lead to unauthorized access or control over a system. This may result in data theft, system degradation, or the use of the infected system to launch attacks on other computers.

The other possible choices do not align with the fundamental intentions of malware. For instance, enhancing computer performance would typically be associated with legitimate software aimed at optimization, not malicious programs. Similarly, installing software updates is a common practice for maintaining system health and security, which malware fundamentally opposes. Lastly, providing system diagnostics is a function related to monitoring and evaluating system performance, which malware seeks to undermine rather than promote.
