Actually, you’ll get two messages – one is a receipt, and the other an activation email open the latter. Check your email (the email account you gave under billing details), where you should find an email from Bitdefender. You’ll then see a confirmation screen which offers a tailored installation and setup service – of course, you can safely ignore that, as you’ve got this guide to hand. Click ‘Confirm Order’ to finalize the transaction. Click on the orange ‘Billing and Payment Details’ button, and fill in the requested personal info and your payment details. Click on the ‘Buy Now’ link of the product, and you’ll be taken to the shopping cart. (In this case, we are buying Bitdefender Total Security - if you need help deciding which plan might be best for you, we’ve got an in-depth feature on which Bitdefender antivirus plan to choose.) If you haven't already done so, head over to the firm’s website.
