I have heard that you can get viruses attached to an email. How does this happen. Solutions: Safe email? file attachments: Spreading viruses.
If you think you've received an email message with an attachment containing a virus, please make sure that you do not open the attachment.
To check a file attachment for a virus, you'll need to first save the file to your computer and then scan the file with antivirus software. Don't open the attachment - Save it.
Most viruses are delivered through an email attachment. Attachments that contain viruses are either executable programs (file types: .com, .exe, .vbs, .zip, .scr, .dll, .pif, .js) or macro viruses (file types: .doc, .dot, .xls, .xlt).
The safest way to avoid them is to not open email attachments. To be real safe if you don't know the person sending the email or if you know them, and weren't expecting the email, check with them first.
