The BBB wants to warn unsuspecting consumers about unexpected Valentine’s Day e-cards. They say if you receive the card it may not be from a secret admirer but might instead contain the Storm Worm virus.

The e-mail directs recipients to click on a link to retrieve the electronic greeting card and once the user clicks, malware (malicious software), is downloaded to the Internet-connected device. It is then infected and become part of the Storm Worm botnet.

The BBB says a botnet is a network of compromised machines under the control of a single user. They are typically set up to facilitate criminal activity such as spam e-mail, identity theft, denial of service attacks and spreading malware to other machines.
