Bitdefender is a popular antivirus software that will keep your Mac safe and secure. It’ll stop viruses and spyware, block ID theft attacks, quarantine suspicious documents and so much more. And if you use Parallels or CrossOver to run Windows on your Mac, Bitdefender will still work, because it can protect dual operating systems on one computer. Normally valued at $60, we’re knocking a third off the price and bringing Bitdefender Antivirus to you for only $40. You can grab it here.
