Never send your username/login and password in an email message.
Beware when replying to unsolicited messages. Replying to these messages or going through the process of unsubscribing from lists merely enforces that they have discovered an active e-mail address. Ignore and delete these messages. Only unsubscribe from lists you have knowingly subscribed to or trust.
Beware of links in email messages. Although some may take you to reputable content, others can lead to infected websites or phishing scams asking for your username/login and password.
Beware of any email messages or attachments you are not expecting, even from friends, family, and colleagues. Some viruses can take over email programs and impersonate people you know.
Don not run any executable (programs) received as email attachments. This is not the best way to transmit programs anyways. If you are transferring programs you should “zip” the files before sending.
Turn off the preview pane in your email program. Some viruses can be accidentally initiated by just previewing the message in some older e-mail programs.
Turn off scripting and auto-launch features. Any features that run programs, macros, or scripts within email messages are capable of launching viruses.
If you receive a message from anybody and are told to delete a file on your computer, DO NOT DELETE IT. Chances are it is a hoax. Check with the IT Team if you are in doubt.
Use discretion when forwarding emails. Not everyone appreciates receiving chain emails. Make sure the people you are sending them to don’t mind this type of email. If you receive a virus alert, although you may think you are doing your friends a favour by warning them, you could be feeding hysteria.
