Introduction:

        G-Data Antivirus is a new security product just released in the United States.   The software has garnered a significant amount of attention because of the high detection rates.   In fact, it was one of the best antivirus that PC magazine has ever tested due to it's detection accuracy.  We now take a closer look at G-Data’s antivirus technology.
        One of the first features that stands out with G-Data Antivirus, is that the software utilizes two scanning engines rather than one.  This theoretically allows the antivirus to have higher virus detection rates but also comes with some performance problems (read more below.) G-Data utilizes Bitdefender’s and Avast’s scanning engines simultaneously.  Bitdefender and Avast are well renowned and have some of the highest individual detections rates at 97% and 98% respectively.

Virus Detection Performance:

       As stated last week on how to compare antivirus, G-Data has all of the premier security lab’s certifications.  They include West Coast Labs, ICSA, and Virus Bulletin certified.   In the main antivirus comparison test, AV comparatives, G-Data scored an advanced + rating (the highest rating.) G-Data had an amazing 99.8% accuracy which exceeded all of the other mainstream antivirus products tested.  Not bad for an antivirus that has just become available to the U.S. market.
       I have heard conflicting reports based about G-Data’s false positive rate. Some users have said that there have been false positives.  However, according to the latest antivirus test, G-Data excelled with the least amount of false positives detected.

G-Data's Drawbacks:

       One thing were G-Data fails to perform on, is it’s slower scanning speed.  The software only scanned files for viruses at 8 megabytes per second.  This is about half of what G-Data’s competitors' Avast and Symantec achieved at around 18 megabytes per second.  G-Data states on their website that they have now incorporated multi cpu core scanning (called ParallelScan) in their 2010 version.  However, the improvement has been small even with a dual core processor. Multithreading scanning only reaches about 10 megabyte per second in real world uses.
       In addition to the slower scanning, G-Data also tends to be a resource hog.  The program uses significantly more memory than competing antivirus products.  A lot of users complain that they have trouble running the software on computers with less than 512 megabytes of ram.  Users have reported that the antivirus can sometimes use upwards of 300 MB of memory.  Therefore, G-Data antivirus 2010 should probably on be used on more powerful systems with at least 1 GB of Ram.

Lackluster Product Support: 

       The final problem seems to be product support.  Since the company is in Germany, a lot of users are having problems talking to support agents. Novice users should probably stay with an antivirus that is a little more user friendly.

Conclusion:

       G-data is probably best suited for the security nerd and not the average user.  I say this because the program requirements are too high for the mainstream system and there isn’t sufficient product support.  The program will need some more refining before it can enter the typical computer user’s household.  However, if you want the best antivirus detection available check out G-data.
