File Anti-Virus and Safe Browsing provide real-time computer protection, but we also recommend that you regularly scan your computer for viruses and other computer security threats. Computer scanning is necessary to prevent the spread of malware that has not been detected by the protection components.
The Kaspersky application contains the following built-in scan tasks:
Full Scan
A virus scan of the computer's memory, startup objects, and all internal disks.
Quick Scan
A virus scan of only critical areas of the computer: memory, startup objects, and system folders.
Custom Scan
A virus scan of a specified object (file, folder, internal disk, or removable disk).
External Disk Scan
A virus scan of external disks that is performed when an external disk is connected to the computer.
When the application performs a scan task, malicious objects are recognized through signature analysis. In addition to signature analysis, the Kaspersky application uses heuristic analysis and other scanning technologies.
In the Scan window, click the start button () to start a Full Scan or Quick Scan task.
The scan task starts.
You can also run a Full Scan or Quick Scan task on My Kaspersky. For more information about running a computer scan on My Kaspersky, see the My Kaspersky Help.
In the menu bar, click the application icon and choose Settings.
The application settings window opens.
You can also open this window by clicking the Settings button in the Quick Scan pane of the Scan window.
On the Scan tab, click Schedule.
In the window that opens, select the checkbox next to the name of the scan task you want to start on a schedule.
Configure the scan task frequency and time.
Click OK to save changes made to the scan task schedule.
When an external disk is connected to the computer, the Kaspersky application can automatically start scanning the disk, prompt to scan, or do nothing. You can select one of the options in the settings of the External Disk Scan task.
In the menu bar, click the application icon and choose Settings.
The application settings window opens.
You can also open this window by clicking the Settings button in the Quick Scan pane of the Scan window.
On the Scan tab, in the list on the left, select the External Disk Scan task.
In the When an external disk is connected section, select the action that the application performs when an external disk is connected.
The Full Scan and Quick Scan tasks already contain scan scopes. While performing the Full Scan task, the Kaspersky application scans the computer's memory, startup objects, and all internal disks. While performing the Quick Scan task, the application scans computer memory, startup objects, and system folders. You can change the scan scope of the Quick Scan task.
Note: You can skip scanning of the read-only system volume to significantly reduce scanning time. By default, the application does not scan the read-only system volume when performing a Quick Scan task and does scan it when performing a Full Scan task.
In the menu bar, click the application icon and choose Settings.
The application settings window opens.
You can also open this window by clicking the Settings button in the Quick Scan pane of the Scan window.
On the Scan tab, in the list on the left, select the Quick Scan task.
In the Scan scope section, click Edit.
A window with the list of scan scope objects opens.
Deselect the checkbox next to the object that you don't want to scan when performing a Quick scan task.
Click Save.
If a threat is detected in a file, the application displays a notification and performs the specified action on the object. You can modify the action to perform when an object is detected.
In the menu bar, click the application icon and choose Settings.
The application settings window opens.
You can also open this window by clicking the Settings button in the Quick Scan pane of the Scan window.
On the Scan tab, select a task in the task list.
In the Action section, select the action that the application performs after detecting infected files.
Before attempting to disinfect or delete an infected file, the Kaspersky application saves a backup copy for subsequent restoration or disinfection. A file copy appears in Quarantine. You can try to disinfect this file later by using updated anti-virus databases.
Information about the results of scan tasks and all detected objects is logged in a report.
Note: If any errors occur while running a virus scan task, start the task again. If the new attempt to run the scan also results in an error, contact Kaspersky Customer Service.
