G DATA Software, Inc. is a German company headquartered in Bochum, Germany.G-Data Total Security
is a comprehensive security suite. I have read that it uses two scanning engines, avast and Bitdefender which makes it effective at blocking malware but the detection rate was lower than one would expect. I have also read that it caused system damage during malware removal testing, had a significant impact on system performance and adding or blocking a custom file in the Firewall was cumbersome.
I'm not an advocate of suites. All-in-one tools and suites generally use more system resources than separate programs that do the same task. They tend to have varying degrees of strengths and weaknesses for each feature. In contrast, separate tools are designed, built and maintained with a greater focus in a specific area so they are generally of better quality and more effective at what they are designed to do. This means the program's performance for that particular feature is usually superior than their all-in-one counterpart. Further, all-in-one tools generally do not allow the user as much flexibility in tailoring default settings and usage.
