As far as features go, G Data delivers on a lot of what you'd expect from an extensive suite. G Data's simple, straightforward interface doesn't degrade user experience by hiding security status. Like many other programs, this one uses green ticks or a caption to indicate the security status.
The program also does a great job of spotting and blocking the emergence of new malware. The virus monitor that redirects your internet traffic through G Data's cloud service not only updates the virus definition file but also blocks malware based on the behavior. G Data blocked all of the unknown, new malware we tried to throw at it in our tests. There was just one false positive.
In AV Comparatives' offline detection test, G Data scored even higher than Bitdefender's clone did. This is probably due to the in-house DeepRay engine, which reveals camouflaged malware by analyzing all the actions that such malware usually tries to carry out. It is looking for patterns that suggest malicious intent. For example, changing the settings of other programs, or observing keystrokes.
The program falls short in certain areas we believe are important to an anti-virus suite. The program does not include a firewall, VPN, or parental controls. If you need these extras G Data's Internet Security package is more expensive. This is a significant disadvantage, particularly since top-of-the-line competitors like Norton 360 and Bitdefender offer the same features for a price or less.
