Picking up any of the above mentioned Kaspersky anti-virus software will get you a Muradin Bronzebeard playable hero, and a Magni Muradin skin.
You can either pick the bundle up in retail stores, or online. The Muradin Hero that you get bundled with the Kaspersky software goes for $3.99 and the Magni Skin that goes with him, which you also get for free, goes for $9.99. It is a pretty great freebie bundle to accompany a pretty great game.
Right now you can pick up Kaspersky Total Security multi-device (R399.50) or Kaspersky Internet Security multi-device (R359.50) and get an additional 3 months, on top of your 12, protection for free.
