Be careful with email attachments and untrusted links

Malware is commonly spread by users clicking on a malicious email attachment or a link. Don’t open attachments or click on links unless you’re confident they’re safe, even if they come from a person you know. Be particularly cautious of attachments with sensational names, emails that contain misspellings, or emails that try to entice you into clicking on a link or attachment (e.g., an email with a subject that reads, “You won’t believe this picture of you I saw on the internet!”).
