Viruses in Email Attachments
An email attachment is a file that can be sent with an email message. Attachments can be any type of file including pictures/images, documents or programs.
While there are many different ways a virus can spread, one of the most common ways is through email attachments. These emails can appear in many different forms however they all have a single aim which is to get you to open the attachment in the email.
Here are some easy ways to protect you and your computer from these types of emails:
  • Are you expecting an email from the sender? Does it look genuine?
  • Are there grammatical or spelling errors? While not all malicious emails are like this, it is a frequent trait.
  • Check the attachment name. Most malicious attachments end with one of the following: .exe, .com, .vbs, .lnk, .bat, .zip, .xls, .doc. Some emails attempt to mask the real attachment name by including two file type extensions, example: "invoice.jpg.exe". The last extension is the real one.
  • Ensure you have an up-to-date anti-virus program that has the ability to scan emails.
