The primary function of the Source of Infection clean-up tool is to identify where malicious files are written from. This tool plays a critical role in cybersecurity by tracing the origins of infections within a system, allowing IT professionals to understand how malware infiltrated a network environment. By pinpointing the source, organizations can take appropriate measures to prevent further infections and secure their systems. The other options focus on different aspects of network management and security. Tracking user activity involves monitoring behavior rather than identifying sources of infection. Scanning for hardware vulnerabilities deals with assessing physical or system weaknesses, and managing user account control settings pertains to permissions and access levels rather than addressing malware sources. Thus, option B accurately captures the tool's primary function in combating malware threats.
