McAfee Anti-Virus Scanning Engine 5.7.00 (5700), 5.6.00 (5600)
Multiple McAfee products


This article contains information about releases and how to stop automatic Engine updates from the current Engine to the next Engine version. It also provides links to articles that help you roll back from the next Engine to the current Engine if required. For an explanation of the Engine and its function, see KB52425.

McAfee first releases the Anti-Malware Engine updates for elective download. This allows you to download Engine packages for manual installation over a period of three months. After the three month period, the Engine is put on an AutoUpdate posting. This means that your point product will automatically update to the new release.
