How is Malware Activated?

To activate, most malware requires a key ingredient: people.

Attackers must find ways to trick people into running a malicious file, opening an infected file, or clicking an unsafe web link. Sending a malicious phishing email or engaging in other types of email fraud is one of the most common techniques they use to spread malware.
