An antivirus for your phone or tablet
As the name implies, DU Antivirus - App Lock Free is a free app that provides protection from viruses and other malicious software to the end user. It's ad-supported, and beyond being an antivirus, protects the user's information from anyone who steals or uses their device by locking apps, photos and videos behind the user's password(s).
Keeping everything safe
The gesture-based passwords that DU Antivirus - App Lock Free uses are virtually identical to the password a user can specify on their lock screen. However, DU Antivirus adds these passwords to individual apps. It can also encrypt the user's photos and videos to ensure that even if someone bypasses the locks on their apps, many individual pieces of data can still be protected. Finally, DU Antivirus - App Lock Free can be set to take a photo via the device's camera if an incorrect password is entered, making it easy to know if less-problematic users (like family members) are accessing apps they shouldn't be. It goes without saying that DU Antivirus is also an antivirus, of course. In some rudimentary testing it both found and eliminated many common Android viruses.
A mostly clean solution for a clean device
The app's interface is similar to most other antiviruses, and anyone that's used a security suite on a desktop, phone or tablet will feel right at home. This includes many of the more common problems with antivirus interfaces: the program is willing to label your phone or apps "at-risk" when the problems you have may be comparatively minor. Some of its functions are harder to find than others as it provides a high level of detail. As an ad-supported app, it occasionally suffers from deceptive ads that provide their own false virus warnings. The developers are usually quick to remove these deceptive ads if they are submitted by users, meaning that this problem is not native to DU Antivirus nor is it intended by the developers, but it is still something to note. On the other hand, DU Antivirus allows the user to perform one-tap scans that are fast and efficient, and most of its default settings mean that usability is typically not a problem.
Two effective security measures in one
DU Antivirus - App Lock Free does what its name implies: it's an antivirus that locks apps. It fills both of those roles very, very well, and while it doesn't include a firewall, that doesn't change how it performs in its other security-related roles. It's a specialized piece of software, but not so specialized you won't find it useful. Whether stamping out a virus that found its way onto your device, or preventing nosy children or malicious thieves from using your phone, DU does what it's supposed to. Give it a try today!
