Buy BitDefender® Total Security 2011 or BitDefender® Internet Security 2011 or BitDefender® Antivirus Pro 2011 or Antivirus for Mac or Antivirus for Mac and PC for only $9.95 AUD each. It also includes free upgrade to 2012 versions. This is an electronic download. You can also buy a DVD backup for $9.97 AUD.
They accept paypal as payment and the usual credit cards.
I am aware that this is a pretty newb question to ask but bare with me, if I buy the DVD backup does that mean I can install it onto multiple PCs, or will it just be locked to the one regardless?
