.KDC File Extension

Update file used by Kaspersky Lab's system security software; contains virus definitions that are used for detecting and quarantining viruses; may also be used during the system rescue process for removing malicious software; may be downloaded periodically for keeping the software and definitions up-to-date.

KDC files are commonly named with a three-letter prefix followed by a three-digit counter for the file update number (i.e., base001.kdc, base002.kdc, etc.).

In Mac OS X, KDC files are located within the /Library/Application Support/Kaspersky Lab/KAV/Bases/ directory.

NOTE: Antivirus definitions are also referred to as "bases" for Kaspersky antivirus software products.
