If you get an email with the subject line “Valentine’s Day eCard !” that looks like it came from AmericanGreetings <services@americangreetings.com>, it’s most likely a virus. I’m not even going to take a chance by clicking the link. The link appears to be to the americangreetings.com domain, but if you hover your mouse over it you’ll see that it’s really going to a different URL. Trickery!
