McAfee

McAfee makes consumer security software for computers, phones and tablets, best known for its antivirus and online protection products. Buying a McAfee card gives you a product key you apply to your McAfee account instead of paying at the checkout. This card is listed for Brazil. Once you have the key, go to mcafee.com/activate and follow the steps there to redeem it and set up your protection. It suits anyone who wants McAfee software without entering card details on the McAfee site, and it works as a gift for a family member or friend who handles their own installation.
