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, especially if SpIDer Guard has been deactivated for a while. Usually the express scan is sufficient for this purpose.

Scanning

To scan the system, on the Dr.Web main screen, select Scanner. Then on the Scanner screen (see Figure 14), do one of the following:

•To scan only the installed applications, select Express scan.

•To scan all the files, select Full scan.

•To scan files and folders of your choice, select Custom scan, then select objects from the list (see Figure 15). To select all objects in the current location, use the check box at the top right. Then tap Scan.

If your device is rooted, you can also scan the /sbin and /data folders located in the root directory.

On devices with Android 11.0 or 12.0, to scan the /Android/data and /Android/obb folders, a permission is required for Dr.Web to access these folders.

To grant the permission to access /Android/data or /Android/obb

1.Tap Custom scan.

2.Select the /Android/data or /Android/obb folder on the list of objects.

3.In the dialog window, tap Grant.

4.Tap Use this folder.

On devices with Android 13.0 or later versions, the /Android/data and /Android/obb folders are system-protected and thus cannot be scanned.

If Dr.Web Scanner detects threats, the  icon appears at the bottom of the scan screen. Tap the icon to open check results (see Figure 16) and neutralize threats. If you switch to another screen or application, you can open check results by tapping the icon on the notification bar.

Sending suspicious files to the Doctor Web anti-virus laboratory

You can submit suspicious ZIP archives (files with the .jar and .apk extensions) presumably containing viruses, .dex, .odex, .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 15), 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.

Dr.Web Scanner settings

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

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