What is Email Attachment Safety about?
Email Attachment Safety is subtitled Dangerous File Types, Verifying a Sender, and the Three-Second Pause. The file sitting in your inbox is still the most common way trouble reaches a computer. This plain-language manual walks you through that file, calmly and completely, so you can tell a harmless document from a dangerous one before you double-click. It opens by explaining why an attachment is still the front door, then covers the two kinds of harm a file can do and why only one of them can be scanned.
