I opened the attachment and I don't know the sender, the subject matter does not make sense, the attachment was odd and the message was strange - the sentences did not make sense - it was as if the writer did not know English very well. What should I do?
You should never open attachment in an email if
1. you don't know the sender
2. The subject lie doesn't make sense
3. The attachment name is suspicious
4. The written words in the attachment don't make sense.
