What should you do if a friend sends an electronic Hallmark greeting card to your work email and you need to click on the attachment to see the card?

Delete the message: This one has four big risks:

1. Some attachments contain viruses or other malicious programs, so just in general, its risky to put unknown or unsolicited programs or software on your computer.

2. Also, in some cases just clicking on a malicious link can infect a computer, so unless you are sure a link is safe, dont click on it.

3. Email addresses can be faked, so just because the email says it is from someone you know, you cant be certain of this without checking.

4. Finally, some websites and links look legitimate, but theyre really hoaxes designed to steal your information.
