Malware defense refers to the strategies and tools used to protect computers and networks from malicious software, commonly known as malware. This includes viruses, worms, trojans, and ransomware, which can damage systems, steal data, or disrupt operations. Effective malware defense involves using antivirus software, firewalls, and regular system updates to identify and eliminate threats. In addition to software solutions, user education plays a crucial role in malware defense. Teaching individuals about safe browsing habits, recognizing phishing attempts, and avoiding suspicious downloads can significantly reduce the risk of infection. Together, these measures create a comprehensive approach to safeguarding digital environments from cyber threats.
