Scan tasks
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.
