In addition to the real-time computer protection provided by File Anti-Virus and Web Anti-Virus, you are advised to 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.
Kaspersky Internet Security contains the following integrated scan tasks:
-
Full ScanA virus scan of memory, startup objects, and all internal drives of the computer.
-
Quick ScanA virus scan of only critical areas of the computer: memory, startup objects, and system folders.
-
Custom ScanA virus scan of a specified object (file, folder, drive, or removable drive).
Each scan task is performed within a specified scan scope and is started manually. Malicious objects are recognized through signature analysis. In addition to signature analysis, Kaspersky Internet Security uses heuristic analysis and other scanning technologies.

- A status that indicates the type of the malicious program detected (for example, virus or Trojan).
- Probably infected status, if the scan cannot determine whether or not the file is infected. The file may contain a code sequence that is typical of viruses and other malware, or modified code from a known virus.
