How does malware typically compromise a computer system?

Malware typically compromises a computer system by exploiting system vulnerabilities. This occurs when malicious software takes advantage of flaws or weaknesses within the operating system, applications, or network protocols. These vulnerabilities may exist due to outdated software, unpatched security issues, or improper configurations. Once the malware successfully exploits a vulnerability, it can engage in various harmful behaviors, such as stealing sensitive data, corrupting files, or gaining control over system resources.

In contrast, the other options suggest beneficial actions, such as enhancing performance, providing security features, or improving user control over applications, which are not characteristics of malware. Instead, malware's core aim is to disrupt, damage, or gain unauthorized access to computer systems, making the selection of exploiting system vulnerabilities the most accurate answer regarding how malware operates.
