A step up is a $80 suite named Bitdefender Internet Security that adds parental controls, a two-way firewall and other features. Bitdefender, for example, has a $60 yearly subscription package (for three PCs) called Bitdefender Antivirus Plus. There are usually three levels of paid-subscription packages. It also opens suspicious programs in an 'sandbox' environment so they don't infect your PC. Paid programs generally offer a slew of additional features, which can be helpful or overkill, depending on what kind of computer owner you are - cautious or geeky.Īvast's Premium Security package ($39.99 for one PC for one year), for example, has several features lacking in the company's free version, such as webcam protections to stop snoopers and a file shredder. There are dozens of paid antivirus programs from such well-known names as Bitdefender, McAfee, Norton and Kaspersky.
