There are a couple of free anti-virus programs that I am using that (so far) have been effective in catching the viruses before they infected my computer. One is called Inoculate-T, the other ZoneAlarm. Also, in order to unthinkingly open a msg with an attachment I created a folder "Attachments to Check". So any message with an attachment is automatically sent to that folder where I carefully check the contents. I don't know if you can do that with all e-mail programs. I use Outlook Express. Shirley
