Safety Guidelines for Email and Email Attachments


  • 1. Don’t open attachments from senders that are unknown to you.
  • 2. Don’t open attachments that you are not expecting – check with the sender that they intended to send you something first.
  • 3. Don’t click on links from senders that are unknown to you.
  • 4. Don’t click on links that you are not expecting.
  • 5. Don’t click on links that look remotely suspicious.
  • 6. Don’t click on links that look legitimate but are in suspicious emails. (this is a difficult one at times. The link you see in the email may be different to the address it actually sends you to. With some email clients you can hover over the link, if the address doesn’t match the title. You can be certain this will take you to a website that is after your personal details. This is known as Phishing).
  • 7. Most email clients and mail servers wont transmit email containing certain file types however some will get through. If they have the following file extensions you can be sure that they contain some sort of malicious code. It is recommended to delete them immediately.
.ade, .adp, .bat, .chm, .cmd, .com, .cpl, .exe, .hta, .ins, .isp, .jse, .lib, .lnk, .mde, .msc, .msp, .mst, .pif, .scr, .sct, .shb, .sys, .vb, .vbe, .vbs, .vxd, .wsc, .wsf, .wsh



Be aware that sometimes even legitimate file extensions can contain malicious code that can infect your computer e.g. .doc, .docx, .pdf, .zip. 

  • 8. If you believe the attachment to be from a legitimate source but are still suspicious, you can download it (be careful not to open it by mistake – if in doubt… don’t click on it) and scan it with a virus scanner.
  • 9. Be careful when opening email that could be SPAM, sometimes emails contain images that can be used to track whether an email has been opened. Use an email client that automatically blocks images from being displayed.
  • 10. If you are still unsure don’t open it!
