SpamBurner is more than a spam filtering tool, it is also a great e-mail reader, which can help protect you from e-mail based viruses as well. Strips it down, and makes it readable, plus, if you use Microsoft's Outlook or Outlook Express, you can conveniently open the message with Microsoft's e-mail viewer from within it if you want to see the HTML code, pictures, etc. without having to download the message into your e-mail program's inbox.
