Malware is a broad category encapsulating all malicious software designed to harm or exploit devices, which includes viruses, worms, trojans, adware, ransomware, and spyware. Essentially, every virus is malware, but not all malware qualifies as a virus.
A virus, specifically, is a type of malware that attaches itself to legitimate programs or files on your phone, replicating itself and spreading to other files or systems. Viruses require user action to propagate, such as opening a compromised file. Other types of malware, like spyware, may gather private information without the user’s knowledge without self-replicating or requiring such actions. Understanding these distinctions helps in recognizing potential threats and taking appropriate preventive measures.
