Viewing email on iPhone and preview of attachments with regards to virus/malware
I recently opened an email on my iPhone. Many times when you open an email on an Macbook, iPad or iPhone it will show you a preview or a snapshot of what is in the attachment. For instance, if a photo is attached to the email, it will show you the photo without you opening the attachment, or what is in a Word Document.
I did not click open the attachment, but when I opened the email itself, it had in the body of the email about 3 pages worth of random letters and numbers, starting with "DQo8IUPRQ1...". It looked to be a .txt file (but I understand other types of files can be made to look like a .txt file)
Again, I did not open the attachment, but the fact that the "information" from the attachment showed in the body of the email, it makes me very nervous about a virus or malware being on my iPhone or iPad.
Can you explain if you need to specifically open the attachment of an email for a virus/malware to take place? Is there any harm from just opening an email that has a virus attached to it and seeing the contents of the file in the body of the email?
Little panicked, so thanks in advance for your help!
