These days, spammers are trying all kinds of ingenious ways to get you to either part with your personal information or open an attachment that could potentially contain a virus. The emails I’ve been getting lately have been from someone described as a friend or a former classmate or relative who has sent me a greeting card. The actual name of the person is never mentioned and there is an attachment for me to open if I want to see the card and the name of its sender. I’ve made it a rule never to open attachments, but there are times my curiosity almost gets the better of me. Then I remember that curiosity killed the cat.
