DU Antivirus is basically a free application that provides virtual protection for your Android devices. It shields your mobile from dangerous viruses and malicious software that can plague your system unchecked, and since it is free, it also supports advertising. The application comes pre-installed with Android OS 4.4 " Kit Kat", so it will not overwrite any existing data or cause any issues with your device's settings or capabilities. Once you download and install DU Antivirus on your phone, it will create a customized user interface which makes it very easy to use.
It works well as a primary or backup anti-malware solution. It has the ability to scan all the important directories and files that store the important settings and information for your phone. With a single click, it displays a list of all the files that are infected and the reason why they are infected. As a backup antispyware program, it backs up your phone so in the case of an unexpected event, you can still restore the data using the built-in restore options in the DU Antivirus app. It also has an in-built firewall to monitor all the activities on your device and prevent harmful viruses and malware from installing themselves on your phone.
There are many other similar programs such as Mobile Manager, My Security Express, McAfee VirusScan Pro, AVG Antivirus for Smartphones etc, but none of them provide the kind of features and protection that DU Antivirus offers. All the other anti-malware programs are either free or have a trial version. Since it is an "app" (application software downloaded directly to your mobile device), it is one of the best ways to stay protected from malicious software, since there are no ads or complications associated with the "app".
