Dr.Web Scanner: On-Demand Scan

On-demand scan of the file system is provided by Dr.Web Scanner. It performs express or full scan of the whole file system or scans critical files and folders only.

You should scan the system periodically, especially if SpIDer Guard have not been active for a while. Usually, the express scan is sufficient for this purpose.


In the central protection mode, Dr.Web Scanner settings may be modified or blocked for compliance with your company security policy or according to the list of purchased services. The scan may start in accordance with a schedule set by network administrator.
