What impact does malware typically have on a computer system?

Malware typically compromises the security and functionality of a computer system. This malicious software can take various forms, such as viruses, worms, Trojans, ransomware, and spyware, each designed to exploit the system's vulnerabilities. When malware infiltrates a system, it can lead to unauthorized access, data theft, system damage, or even complete system failure. The primary goal of most malware is to disrupt normal operations, manipulate system settings, or exfiltrate sensitive information, which highlights its role in undermining both security and functionality.

The other choices suggest positive outcomes that malware does not provide. For example, enhancing system efficiency or improving user experience contradicts the fundamental purpose of malware, which is inherently disruptive and malicious. Additionally, assisting in data organization and management misrepresents the intent of malware, as it ultimately leads to chaos rather than improved data handling. Thus, the selection that identifies malware as compromising security and functionality accurately reflects its detrimental effects on computer systems.
