Malware detection is the process of identifying malicious software such as viruses, worms, trojans, ransomware, and spyware on a computer system or network. This process typically involves scanning files, programs, and system activities for suspicious behavior or known malware signatures. Modern malware detection methods combine signature-based techniques with advanced approaches like heuristic analysis, machine learning, and behavioral monitoring to recognize both known and emerging threats. Effective malware detection is essential for maintaining cybersecurity, preventing data breaches, and ensuring the integrity of digital environments.
