Dr.Web Scanner: On-Demand Scan

On-demand scan of the file system is performed by Dr.Web Scanner. It can execute an express or full scan of the whole file system or scan critical files and folders only.

It is recommended to scan the system periodically. Usually, the express scan is sufficient for this purpose.

Scanning

To scan the system, on the Dr.Web navigation panel, tap scannericon, then on the Scanner screen (see Figure 5) select one of the following actions:

To scan only the installed applications, select Express scan.

To scan all the files, select Full scan.

To scan only selected files and folders, select Custom scan, select the objects from the list (see Figure 6). To select all objects in the current location, use the check box at the top right. Then tap Scan.

On devices with Android 11.0 or later, the /Android/data and /Android/obb folders are system-protected and thus cannot be scanned.

If Dr.Web Scanner detects threats, the indicator in the center of the screen turns red. Tap the indicator or the number of detected threats to open scan results (see Figure 7) and neutralize threats. If you switch to another screen or application, you can open scan results by tapping the icon on the notification bar.

Sending suspicious files to Doctor Web anti-virus laboratory

You can submit suspicious ZIP archives (files with the .jar and .apk extensions) presumably containing viruses, .odex, .dex, .so files, or clean ZIP archives that have been identified as so-called false positives, to the Doctor Web anti-virus laboratory.

To send a file to the laboratory

1.Tap and hold the file in the hierarchical list (see Figure 6), then tap Send to laboratory.

2.On the next screen, enter your email address if you want to receive the results of the file analysis.

3.Select a category for your request:

Suspicious file if you think that the file is a threat.

False positive if you think that the file was identified as a threat by mistake.

4.Tap Send.

The Doctor Web anti-virus laboratory accepts files of 250 MB or less.

Dr.Web Scanner settings

To access Dr.Web Scanner settings, open the Settings screen and select Scanner.

To enable scanning of files in archives, select the Files in archives check box.

warning_green

By default, the scanning of archives is disabled. Enabling archive scanning may impact system performance and increase power consumption. Disabling archive scanning does not decrease the protection level because Dr.Web Scanner checks APK installation files even if the Files in archives check box is not selected.

To monitor changes in the system area, select the System area and Any files in system area сheck boxes. If the setting is enabled, the component monitors changes (addition, modification, and deletion of files) and notifies only on deletion of any files as well as addition and modification of executable files: .jar, .odex, .so, APK, ELF files, etc.

To enable/disable detection of files that might threaten your device, select the corresponding check boxes:

oSuspicious objects,

oAdware,

oDialers,

oJoke programs,

oRiskware,

oHacktool programs,

oExploitable software.
