Dr.Web anti-virus performs diagnostics of the security of your device and helps resolving the detected problems and vulnerabilities using a special component - Security Auditor. This component is enabled automatically when the application is launched for the first time and after registering the license. The number of the detected problems is displayed on the section of the main application screen.
Resolving security problems
Figure 17. List of security problems detected on the device
Dr.Web anti-virus detects the following categories of security problems: applications with highest priority of SMS processing, hidden device administrators, vulnerabilities and system settings that affect 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.
This category contains the list of the applications installed on the device that have the higher priority in SMS processing than Dr.Web anti-virus. Such applications can block the operation of and , since they are first to process all incoming messages and . Sometimes such applications are malicious and may present a threat to the security of your device.
If you notice that the SMS filtering or Dr.Web Anti-theft does not work properly, try to change the priority settings of the applications in the list, if possible. These applications will disappear from the list of security problems. If you are not sure that these applications are totally safe, it is recommended to delete them from the device. To delete an application, tap on the screen with the detailed information on the problem related to this application, or use the standard OS tools.
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 dangerous.
If you don't know why such application is not displayed in the list of device administrators, it is recommended to delete it from the device. To delete an application, tap on the screen with the detailed information on the problem related to this application.
USB debugging and installing applications from unknown sources are the system settings that affect the security of the mobile device:
• is intended for developers and allows copying data from PC to the mobile device and vice-versa, installing the applications on the device, viewing their logs and deleting them in some cases. If you are not developer and do not use the debug mode, it is recommended to turn it off. To open the corresponding device settings section, tap on the screen with detailed information on the problem.
• is the main source of threats. Application downloaded from other source that official market (Google Play) are likely to be unsafe and present a threat to the mobile device security. To mitigate risks of installing the unsafe applications, it is recommended to disable installation of the programs from unknown sources. To open the corresponding device settings section, tap on the screen with detailed information on the problem. It is also recommended to scan for viruses all the applications you install on your device. Make sure that Dr.Web virus databases are before scanning.
Dr.Web anti-virus detects such vulnerabilities as Master Key (#8219321), Extra Field (#9695860) and Name Length Field (#9950697) in the device system. They allow adding malicious code to some applications without changing their cryptographic signatures, that may result in acquisition of dangerous functions by these applications and damage the device. Check for operation system updates on the official web site of your device manufacturer. Newer versions may have this vulnerability fixed. If there are no updates yet, it is recommended to install applications only from trusted sources.
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 rooted your device yourself, it is recommended to 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.
