UPDATE: Google has removed all apps from Security Master’s parent company Cheetah Mobile for repeated violations of Google’s advertising policy. As such, we can no longer recommend them here. That said, even before the removal, Security Master didn’t offer great protection. There are plenty of better free Android antivirus apps to download. Original Review: Security Master might not be the “number one antivirus” on the market, but there’s plenty of value to make this tool a part of your Android handset. It has some unique features on top of its highly-rated antivirus scanner and has been thoroughly tested.
