Kaspersky Internet Security 2012

Experts haven't been completely taken with Kaspersky's firewall, but that's changed in Kaspersky Internet Security 2012. It's the only 2012 Internet security suite that garners an Excellent rating in Matousec.com's stringent firewall testing, and the defense holds up just as stoutly for other reviewers. Some critics want Kaspersky to stealth all open ports; if it doesn't, outside attackers can see your PC during scans. But even the staunchest of critics say the firewall is nearly impenetrable. The antivirus capabilities shine in testing, as well, although Kaspersky's anti-spyware chops aren't as effective as Norton Internet Security 2012's (*Est. $70).

Critics say they appreciate the clean, simple installation process and user interface, which has been overhauled compared to previous versions. Kaspersky Internet Security 2012 doesn't impair computer performance once your PC's up and running, but reviewers warn that it will slow down your boot time. Kaspersky's tech support outshines the paltry help available to users of Comodo Firewall, which reviewers name the most effective firewall. Kaspersky owners have access to support via an included user guide and an online knowledge base and forum; and they have official help via live chat, email, telephone and Kaspersky's social media accounts.
