Security Auditor

Top  Previous  Next

Dr.Web uses a special component — Security Auditor — to diagnose the security of your device and help resolving the detected problems and vulnerabilities. The component is enabled automatically when the application is launched for the first time and after registering the license.

Resolving security problems

To review the list of the detected problems and vulnerabilities (see Figure 26), select the Security Auditor section on the application main screen.


Figure 26. Detected security problems

Dr.Web detects the following categories of security problems:

Applications with the highest priority of SMS processing.

Hidden device administrators.

Vulnerabilities and system settings that affects the device security.

To view the detailed information on any detected problem and to resolve it, open one of the categories and tap a problem in the list.

Hidden device administrators

Applications that are activated as device administrators but not shown on the list of administrators on the corresponding section of the device settings cannot be deleted by means of the operation system. Most likely, such applications are potentially harmful for your device.

If you do not know why an application is not displayed in the list of device administrators, you are recommended to delete it from the device. To delete the application, tap Delete on the screen with the detailed information on the problem related to this application.

System settings

Security Auditor detects the following system settings that affects the device security:

USB debugging. This mode is intended for developers and allows copying data from PC to the device and vice versa, installing the applications on the device, viewing their logs and deleting them in some cases. If you are not a developer and do not use the debug mode, you are recommended to turn this mode off. To open the corresponding device settings section, tap Settings on the screen with detailed information on the problem.

Installing application from unknown sources.This is one of the main reasons devices running Android 7.1 and earlier get infected.

Applications downloaded from elsewhere other than the official store are likely to be unsafe and become a threat to device security. To mitigate risks of installing the unsafe applications, you are recommended to disable installation of the applications from unknown sources. To open the corresponding device settings section, tap Settings on the screen with detailed information on the problem.

You should scan for viruses all the applications you install on your device. Before scanning, make sure that Dr.Web virus databases are up to date.

Software conflicts. Use of conflicting software, including web browsers that are not compatible with URL filter, decreases the security level of your device. While using these browsers you will not be protected against the undesirable and malicious web resources. We recommend that you make one of the following browsers default on your device: Android embedded browser, Google Chrome, Yandex.Browser, Microsoft Edge, Firefox, Opera, Adblock Browser, Dolphin Browser, Sputnik, and Boat Browser.

Dr.Web notifications are blocked. When notifications are blocked, Dr.Web cannot immediately inform you on detected threats. This compromises security of your device. That is why, you are recommended to enable Dr.Web notifications in the settings of your device.


Vulnerability is a weakness in the source code which allows cybercriminals to impair the correct operation of a system.

Dr.Web detects the following vulnerabilities in the system: BlueBorne, Master Key (#8219321), Extra Field (#9695860), Name Length Field (#9950697), Fake ID (#13678484), ObjectInputStream Serialization (CVE-2014-7911), PendingIntent (CVE-2014-8609), Android Installer Hijacking, OpenSSLX509Certificate (CVE-2015-3825), Stagefright and Stagefright 2.0, SIM Toolkit (CVE-2015-3843). They allow adding malicious code to some applications, that may result in acquisition of dangerous functions by these applications and damage the device. Dr.Web also detects the Heartbleed vulnerability — an error in OpenSSL, that can be used by cybercriminals to access user confidential information.

If one or more of these vulnerabilities are detected on your device, check for operation system updates on the official website of your device manufacturer. Recent versions may have these vulnerabilities fixed. If there are no available updates, you are recommended to install applications only from trusted sources.

Applications exploiting Fake ID vulnerability

If applications exploiting Fake ID vulnerability are detected on the device, they are displayed in the separate Security Auditor section. These applications can be malicious, therefore you are recommended to delete them. To delete the application, tap Delete on the screen with the detailed information on the problem related to this application, or use standard OS tools.

User certificates

If any user certificates are detected on your device, Security Auditor detects and displays them. Certificates may be used by a third party to monitor your network activity. If you are not aware why these certificates are installed on your device, you are recommended to remove them.

Root access

The device may become vulnerable to different types of threats if it is rooted, i.e. the procedure of rooting has been performed to attain control (known as root access) over the device system. It results in ability to modify and delete system files, that may potentially damage the device. If you have rooted your device yourself, rollback the changes for security reasons. If root access is the integral feature of your device or you need it for your everyday tasks, be extremely cautious when installing applications from the unknown sources.
