G Data InternetSecurity 2013 ($35 for one year, as of 12/19/12) is a comprehensive security suite with an excellent protection record: It blocked, detected, and disabled all of the malicious files we threw at it, and cleaned up 80 percent of infections in our system cleanup test. However, it's not the most user-friendly suite, with a tedious installation process and an advanced-users-only settings panel. As a result, it ended up toward the bottom of our rankings.
In our real-world attack test, G Data completely blocked 100 percent of attacks. This indicates how well the product will successfully block brand new malware attacks when it encounters them in the wild. Of the nine security suites we tested, five completely blocked all attacks: G Data, F-Secure, Bitdefender, Norton, and Trend Micro.
