![]() Its score of 3.0 points barely escapes being the lowest ever. Including all twelve systems, Sophos detected 53 percent of threats, the lowest detection rate among products tested with my current malware collection. Under my previous malware collection, Norton AntiVirus 2012 ($39.99 direct, 4.5 stars) managed 7.1 points, Webroot SecureAnywhere Antivirus ($39.95 direct, 4.5 stars) took 6.9, and the free, cleanup-only Comodo Cleaning Essentials (free, 4.5 stars) managed 6.8 points.Ĥ.7 points would be an okay score for Sophos, but that doesn't factor in the systems where Sophos couldn't complete a full scan. The highest score achieved using my current malware collection was 5.6 points by Emsisoft. On the systems where it managed to finish a scan, Sophos detected 81 percent of the threats and would have scored 4.7 points for cleanup. So, for one reason or another, Sophos couldn't do anything at all to clean up half of my twelve malware-infested test systems. I let it go through this cycle six times before concluding that it really, truly was not ever going to finish a scan. After rebooting, Sophos detected the malware, offered to clean it, and requested another reboot. Sophos detected it, offered to clean it, and requested a reboot. Sophos can't install in Safe Mode and hence didn't clean this system at all.Īnother test system displayed a different kind of problem with in-memory malware. However, one of my test systems can only run in Safe Mode because a ransomware threat totally takes over if it boots into normal Windows. Installation is quick and easy, when it works. Unlike Emsisoft Emergency Kit 2.0 (free, 3.5 stars), another free, cleanup-only antivirus, Sophos needs to be installed before you can use it. With another product doing the heavy lifting, Sophos might well find leftover malware scraps. It's perhaps telling that the use-case described in the Naked Security post (Opens in a new window) involves running Sophos after another antivirus. Typically you'll grab a free cleanup-only tool when malware on the PC prevents installation of a full-scale desktop antivirus. That may well be, but in my own testing Sophos alone did a really terrible cleanup job. ![]() Could not complete a scan on six of twelve infested systems.Ī recent post on Sophos's Naked Security blog celebrated the updated Sophos Virus Removal Tool 2.0 (free), noting that for 27 percent of users it found threats other antivirus products missed.No updates must re-download on each use.Unlike most cleanup-only tools, it requires installation.How to Set Up Two-Factor Authentication.How to Record the Screen on Your Windows PC or Mac.How to Convert YouTube Videos to MP3 Files.How to Save Money on Your Cell Phone Bill.How to Free Up Space on Your iPhone or iPad.How to Block Robotexts and Spam Messages.
