I can't say enough good things about Bitdefender. They have been protecting my iMac, iPad and iPhone for several years and I've had zero issues. Unlike some antivirus software, Bitdefender runs smoothly without any complications 24/7. If you need to contact their customer service department, you will find their representatives friendly, very knowledgeable and easy to work with. Their costs have increased a bit over the years, but I do not mind and I'm willing to pay whatever the charge is each year when I renew because this company does such an outstanding job of protecting my devices. They are worth every penny you will spend, believe me. I highly recommend this company to protect your devices without worry or stress.
