How to Secure Your Computer: Maxim #6

I get questions all the time from clients over at Ask the Geek about using a mail client’s message preview feature. Opinions vary, of course, but for this geek, it’s a bad idea. In order to preview a message, it has to be opened or rendered by the HTML engine. Think about how a PC can be infected by a malicious web site and you’ll immediately understand the danger: The same malicious programs can exist in scripts in HTML messages. It’s a serious security risk.

Always disable any message preview or auto-open features in your e-mail client. As an added layer of protection, view messages as text-only until you know they are safe.

Cheers!
