Chock full of cute animation, upbeat music and sweet sayings, sending an e-card may charm Mom into thinking it?s OK you didn?t get her an actual present. But that cute e-card could also harbor viruses or spam that could charm their way into Mom?s computer system, destroying everything in their path.

According to the Greeting Card Association, 420 million e-cards will be sent this year, and Mother?s Day is one of the busiest times. While that means lots of mothers will be laughing or crying depending on what selection you chose, it also means that hackers are trying to lure you into picking a card that opens a virus, spam or spyware.
