Which best describes the function of antimalware solutions?

Antimalware solutions are specifically designed to identify, detect, and eliminate various types of malware threats, which include viruses, worms, Trojans, ransomware, spyware, adware, and more. Their primary function is to serve as a protective measure that ensures the integrity and security of computer systems by responding to both known and evolving threats. These solutions commonly employ signature-based detection, heuristic analysis, and behavior monitoring to recognize and tackle potential malware, making them crucial in maintaining a secure computing environment.

While other options mention aspects related to system security and performance, they do not fully encapsulate the comprehensive purpose of antimalware solutions. For example, scanning for known viruses is just one part of detection and is not sufficient for addressing the wide range of malware that can threaten a system. Additionally, unauthorized access protection relates more to firewalls and intrusion detection systems rather than antimalware. Lastly, while some antimalware solutions may have features that inadvertently improve system performance, this is not their primary function or goal. Therefore, the correct answer reflects the integral role of antimalware in combating various forms of malware and ensuring device protection.
