The Scan Engine is central to McAfee Enterprise products that use the Scan Engine. The Scan Engine uses information contained in the DAT files to identify and act against viruses. To view FAQs about the regular DAT files, see: KB55986 - FAQs for V2 DAT files, or KB82396 - FAQs for V3 DAT files.
The Scan Engine is updated frequently to implement new advances in antivirus technology and to provide the greatest level of protection against virus threats. The Scan Engine consists of a binary that contains the program logic to do the following:
- Scan files at particular points
- Process and pattern-match virus definitions with data it finds within scanned files
- Decrypt and run virus code in an emulated environment
- Apply heuristic techniques to recognize new viruses
- Remove infectious code from legitimate files

Is it important to keep my Scan Engine and DAT files up to date?
Updating your DAT files regularly is essential to the security of your environment. Keeping your Scan Engine up to date is equally important.
