Regardless of the attachment of the file you’ve received (by email), it is advised never to open them directly on the e-mail provider (by clicking on it). Rather save onto the hard disk and then scan it with your antivirus. If your antivirus detects a trace of infection, you can erase the virus by deleting the email with the attachment.
