The numerous leftover malware traces earned it an overall score of 7.8 points, with 10 being the maximum. In many cases it left behind executable files. My Symantec contacts confirmed that it doesn't attempt to clean up most Registry traces. However, as with Malwarebytes, its cleanup was spotty. Based on these reports, and on my checking tool's before and after results, I determined that Power Eraser detected 87 percent of the samples, better than the 65 percent detection exhibited by Malwarebytes. Each fix required a reboot, after which Power Eraser ran again to report its success. I had to exempt my checking tool from removal each time before clicking the Fix Now button.

The samples don't always install the same collection of components, so I ran my hand-coded checking tool both before and after the cleanup.Īt the end of each scan, Power Eraser listed its findings. In each case, I first ran the Unwanted Application Scan, and in each case, it found nothing. Then I launch the rest to see whether other forms of real-time malware protection prevent the infestation.Īs I did with Malwarebytes, I tested Power Eraser by installing four samples at a time, waiting for them to be fully active, and then running a cleanup scan. Normally I open a folder of samples and note which ones get eliminated by the on-access scan. I can't test this tool exactly as I do regular antivirus tools. After all, the point of Power Eraser is to handle active malware infestations that your regular antivirus can't. Those scans are interesting, but using them on a system with no active malware isn't a proper test. Not surprisingly, Reputation Scan flagged every single one of them as Unknown, with an option to submit the files to Symantec for analysis. I change the filenames, append zeroes to change the file size, and tweak some non-executable bytes. I mentioned that I have another folder containing the same set of samples, but hand-modified. It only checks the files and folders that you give it.

Note, though, that it's not a full system scan. This scan flagged 83 percent of the samples for removal. When I fed my folder of samples to the Reputation Scan, things got interesting. To my surprise, it reported "No Risks Found." I launched an Unwanted Application Scan just to see what would happen. It also provides a home for a handful of utilities that I wrote to help with testing. My standard virtual machine test system has dozens of ransomware samples on it, along with hand-modified versions of those samples.

Bitdefender Antivirus Plus almost equaled Kaspersky's record, but missed by a half-point on one test.

And Kaspersky Free is a full-scale antivirus, with real-time protection that's not part of Power Eraser. It's worth noting that in the latest set of tests, Kaspersky Free swept the field, with all perfect scores. The fact that Norton's aggregate lab score is a decent 8.8 of 10 possible points just has no bearing on how well Power Eraser works. No Lab Test ScoresĪll four of the independent testing labs that I follow include Norton in their testing, but what they're testing is Symantec Norton AntiVirus Basic A$39.99 Per Year at Norton Australia, not Power Eraser.
