Explanation

E-mail has six strengths. It is fast, because messages arrive in moments. It is cheap, and often free. It is easy, because one message can go to any number of receivers. It is varied, because it can carry text, files and pictures. In most cases the messages arrive reliably. And it lets you sign up for digital services. E-mail also has risks. An account can be hacked, which means a bad person gets in without permission. Spam messages arrive without being asked for. Fraud messages try to trick you. Some messages carry viruses or other harmful programs, often hidden in attachments. And e-mail is not completely private. There is no need to be afraid. Follow a few habits: do not open an attachment from someone you do not know, do not answer a message that asks for a password, and show strange messages to a trusted adult. You are not in trouble when you receive one.

Salma gets an attachment from a sender she does not know. A virus can hide in an attachment, so she does not open it. She tells her teacher. She is not in trouble; the teacher thanks her.
