BitDefender flies in the face of conventional wisdom in more ways than one. Like most security suites, BIS runs the risk of spreading itself too thin by combining antivirus, antispyware, antiphishing, a firewall, parental controls, antispam, and more into a single package. That’s a challenge in and of itself, but BitDefender also attempts to cater to computer users of all skill levels, whether you consider yourself a beginner, intermediate, or expert. A tough challenge, but BitDefender proves up to the task.
