Malware types include viruses (self-replicating code that attaches to programs), trojans (disguised as legitimate software), ransomware (encrypts files for ransom), spyware (covertly monitors activity), adware (displays unwanted ads), and worms (self-propagating network malware). Malware is typically delivered via phishing emails, malicious downloads, or compromised websites.
