Every email user should be constantly on guard against the threat of malware and take personal responsibility for ensuring that individual actions do not compromise the valuable resources of others. Maintain a healthy suspicion with regard to email and confirm the reliability of all attachments before opening them, even if the message is - or appears to be - from someone you know.
Any device accessing the HSU network must have up-to-date virus protection software installed and configured to automatically download new protection mechanisms as soon as they become available.
To prevent the spread of viruses through email attachments, Gmail blocks attachments in those file formats most commonly used to distribute malware. Gmail will block these types of files even if they are sent in a compressed (.zip, .tar, .tgz, .taz, .z, .gz) format. Attempts to send such files will result in a bounce-back to the sender. Microsoft Outlook and Outlook Express also block these same potentially-unsafe file types
If you need to send a file to someone that would otherwise be blocked if sent by email, the best way to accomplish this is to use secure file transfer protocol to upload the file to your Network Folder.
