Editor’s Note: Top Ten Reviews uses test results from the independent laboratory AV-Test as part of our review process for the best anti-malware software. AV-Test looks specifically at protection, performance and usability on multiple versions of Windows operating systems, and it performs these evaluations several times throughout the year. We use the most current AV-Test scores available at the time of our review. It is possible that new AV-Test scores will be released after our review goes live on the site. We will consider these scores during our next review of the best anti-malware software.
G Data Antivirus for Windows is anti-malware software that protects your computer from a number of threats, including viruses, Trojans, spyware, rootkits and keyloggers, though not ransomware. It performed adequately in AV-Test's protection and usability tests, but performance issues weighed down its overall results.
AV-Test is an independent, impartial organization that tests every anti-malware program on our lineup every few months. At the time of this writing, G Data Antivirus for Windows had scored 92 percent when tested against more than 14,000 malware threats new and old. This was the average score among the products on our side-by-side comparison chart. The programs in the top tier of our review all earned 100 percent.
Another test conducted by AV-Test measures how much computer resources each anti-malware program uses. Software that hogs processing power has the potential to slow down the other things you're doing on your computer. You're likely to experience at least some delay in your downloads, uploads, other applications, streaming content and more when this software is in use. The best malware removal software programs we reviewed provide a seamless experience without sacrificing performance.
This anti-malware software offers a few features that other products do not, such as mobile phone protection and hourly virus signature updates. For its more basic features, G Data can secure emails, chat conversations, online shopping and web surfing. It can also manage custom scans and allow/block lists, letting you hand-pick some of the things it stops or lets through.
These tools are good as far as they go, but G Data leaves out some of the key anti-malware tools we look for in our review. For example, it does not protect you against ransomware, which is when hackers take control of your computer from afar and hold it hostage until you pay them. The program also doesn't automatically scan USB drives when you plug them into your machine. To make sure your external devices are safe, you have to run a manual scan after you've connected them – when it may be too late to keep your computer from becoming infected.
Should you need assistance, you can contact customer and technical support by telephone or email. The software includes embedded help files, but the website does not include much product information. If you really need help with your G Data product, it appears that calling the company directly is the best option. It provides U.S.-based telephone support during standard business hours EST.
G Data Antivirus for Windows ranks in the bottom tier in our review of the best malware removers for several reasons. Chief among them is the fact that it slows your computer down while it's in use. Also, even though it protects your computer from most malware threats, it lacks the ability to detect and remove ransomware from your system and to auto-scan USB drives. The best programs on our lineup offer all these things and more.
