What is the primary function of anti-malware software?

The primary function of anti-malware software is to find and stop malware. This type of software is specifically designed to detect, prevent, and remove malicious software from computers and networks. Malware can include viruses, worms, trojans, ransomware, and spyware, which can compromise the security of a system, steal data, or cause damage. Anti-malware software scans files and programs for signatures of known malware and uses behavioral analysis to identify suspicious activity, thereby protecting the user's system from potential threats.

Other options focus on different aspects of system management or optimization, which are not the main roles of anti-malware software. Enhancing system performance, managing user access, and optimizing data storage refer to general system administration tasks and do not directly relate to the detection and prevention of malicious threats.
