The term malware encompasses various malicious software types that threaten computer systems and networks. This includes viruses, worms, trojans, ransomware, and spyware, each designed for different harmful purposes such as stealing data, damaging files, or hijacking system resources. Malware can spread through infected software downloads, email attachments, and compromised websites. Organizations must implement robust security measures, including firewalls, antivirus programs, and user education, to defend against these threats and protect their digital assets.
