About emergency DATs
The SuperDAT executable is a self-installing package. It might also include a new virus-scanning engine and other program components. The file uses the name format sdatXXXX.exe, where XXXX is the four-digit DAT version number, for example sdat4321.exe.
When an EXTRA.DAT file is extracted from the SuperDAT executable and added to the Engine folder on your hard drive, it is used by VirusScan Enterprise, in addition to its normal DAT files, to detect the new virus. This enables VirusScan Enterprise to protect your computer from the new malware code until the official DAT update is released that contains the malware detection and removal information. Once the official DAT update is released and installed, the EXTRA.DAT file is no longer needed.
