I feel better without DU

There's no denying that Android users are at more risk of catching the flu on their devices. Beyond the uncertainty of Google Play, many users are installing their apps from third-party sources, which renders Google's Bouncer algorithm completely useless. I get it. Some apps are not allowed on Play for reasons other than digital security, but the truth of the matter is that the average user hasn't evolved past the level of clicking shiny buttons whenever they show up on screen.

Unfortunately, the general tendency is to install free antivirus apps. I'm not saying these are trojan horses, nor that they are useless. But more often than not, these apps come with a lot of useless chaff. Such is the case with DU Antivirus Security.

DU Antivirus Security

I'm not one to analyze the app's heuristic malware scan, but what struck me as odd with DU Antivirus was that after the first scan it promptly warned me about an "important security risk." That was the fact that DU wasn't handling my apps, photos, and videos, more precisely, that I hadn't enabled locks over everything. Now, I am a conscientious phone user. I don't leave my phone unlocked on the bar table while I'm off taking a leak. In fact, I don't leave it at all. I also don't appreciate having to type in a password or swipe a code whenever I access my email app. I do that often enough with the home screen. So if this is DU's biggest concern, then maybe this app is just blowing smoke.

Looking past this disappointment, the app itself is, predictably, full of hidden ads and fake functions that get you to download additional software.

One quirky feature that I did experiment with was the "DU Swipe." This one creates a sort of widget on the side of the screen, which can be extended to display your apps, device functions, and even some ads on the side. I suppose this Swipe may be useful if you have a million unsorted apps lying around, but I didn't appreciate the commercial nature of the whole thing.

Final Thoughts

Beyond cleaning the cache, old files, and other dusty files, DU Antivirus is more of a gateway for installing additional apps. I can't tell if that software is good or bad because it's not of this app. Just like any free "security" program for Android, DU is good for clearing your device's excess stored memory, but then it doesn't also need to remain installed afterward.
