Dr.Web Anti Virus for Android (Free) offers basic malware protection that includes a real-time scanner for downloaded files, but lacks the more advanced anti-spam and anti-theft features of the paid version. Even so, it proves to be a useful and reliable security app.
Multiple scanning modes: Dr.Web Anti Virus for Android (Free) features a Quick Scan, a Full Scan, and a Custom Scan for examining a specific file or folder, a feature not provided by other mainstream mobile antivirus apps. All scanning modes prove thorough and relatively speedy, a Quick Scan for apps lasting only 35 seconds in our tests. A Full Scan is a lot slower, taking three minutes and 41 seconds for a 16GB tablet.
Effective quarantine: You can delete threats, or you can move them into an easy-to-access quarantine to monitor them. Since the quarantine presents a detailed list of the files it contains and can be accessed through the main app window, it proves to be highly useful in managing potential threats without actually having to delete files that may only be false warnings.
Too lightweight: Even though this app is meant to be a stripped-down version of a complete mobile protection security app, it lacks features like call restriction, SMS blocking, device locking, and data wiping, which other security solutions offer for free. What's more, the app's scanning speed, though good, proves to be slower than that of free solutions from AVG or KS Mobile.
Pestering notification: While real-time monitoring is active, you'll constantly get notifications that try to get you to upgrade to the paid version.
Dr.Web Anti Virus for Android (Free) accomplishes its goal of providing basic protection through scanning and real-time monitoring, proving to be a highly appealing antivirus app for average users. But as the app's description page makes clear, it doesn't offer complete protection, as it's really an enticement to buy the paid version of the app. You can find free security apps that provide more features.
