![]() Spyware Doctor with AntiVirus 2011 ($39.95 direct for three licenses, 4 stars) led the pack with a score of 9.1 points. More than half of the products tested against the previous sample set detected 100 percent of rootkits. Looking specifically at rootkits, G Data detected 86 percent and scored 5.3 points. G Data's relatively low removal score of 5.4 points reflects the fact that it left behind executable traces for over 40 percent of the threats it detected and left behind all non-executable threats for another 28 percent. That's good, but nowhere near the 97 percent achieved by K7 Antivirus Plus 11.0 ($39.96 direct, 4 stars) or the 94 percent detection rate of Double Anti-Spy Professional v2 ($29 direct, 4 stars) (both using the previous set of samples). G Data detected 83 percent of the malware samples. One thing is very clear it's significantly better at detecting threats than at thoroughly removing them. G Data's scores don't necessarily compare directly with those in earlier tests. This is only the second product tested with my 2011 malware collection, and the first was avast! Rescue Disc ($10/once direct, 3.5 stars), which is a cleanup-only CD-based product. All of the systems that hadn't been pre-cleaned by the Boot CD (and a few that had) needed a reboot to finish their cleanup. In most cases it recommended "disinfect (if not possible, quarantine)." For all of the test systems I chose to execute the default actions. When the scan finishes G Data lists the traces it found along with its recommended action. On my standard clean test system the initial scan took 40 minutes while a second scan barely needed 40 seconds. This initial scan takes a while, because it marks each clean file to be skipped on subsequent scans. Once I finally had G Data installed on all twelve test systems I ran a full scan on each. In some cases it quarantined dozens of infected files, wiping out Firefox and parts of Microsoft Office! I expected it to remove the virus, not the entire infected file. ![]() I set it to disinfect files if possible, quarantine if not. Running a scan with the Boot CD did allow me to install the product on all six problem systems. In fact, the product itself contains a wizard that will handle creating and burning a fully up-to-date Boot CD. G Data won't install or scan in Safe Mode, but the company does make a Boot CD available to handle problems like this. Three other systems locked up during the install process, after the reboot stage. On three of the test systems, malware completely prevented installation. That was for the systems on which G Data installed without problems. After a required reboot, each needed a while longer for the necessary initial update. On these underpowered virtual machines the install took quite a while to unpack and run. Getting the product installed on my twelve malware-infested tests systems was something of an ordeal. For details on how I derived this summary, see How We Interpret Antivirus Lab Tests. The chart below summarizes test results for the current crop of antivirus programs. My own tests showed it to be better at keeping malware out of a clean system than at removing already-entrenched malware. It's worth noting that in all three cases G Data's repair score was the lowest of the three. Individual scores for detection, cleanup, and usability go into the AV-Test totals. G Data passed handily, receiving 15.0, 13.5, and 14.0 points in the three tests. 11 total points out of a possible 18 are required for certification. Best Hosted Endpoint Protection and Security SoftwareĪ is running an ongoing series of antivirus certification tests under Windows XP, Windows Vista, and Windows 7.
