>The message is sent through the sender, but the virus is automatically sent with the message because the sender's device is infected with a virus;
>When the sender sends the message, the attachment is actively added, and the attachment file contains the virus.
For the recipient, if you receive these messages carrying malicious code, and the local without the latest, effective anti-malicious code tool, then it will be infected with the virus or Trojan invasion, and so on.
