McAfee Anti-Malware Engine 6400 BETA

McAfee is pleased to announce the BETA for the McAfee Anti-Malware Engine 6400. This will be a new maintenance update to the current Engine 6300. The McAfee Anti-Malware Engine is the core component at the heart of the award-winning McAfee Endpoint and Gateway products. Using patented technology, the Engine analyzes potentially malicious code to detect and block Trojans, viruses, worms, adware, spyware, and other threats.

We encourage you to actively participate in this Beta program and provide us your valuable feedback.

Release availability

The Engine 6400 will be delivered through a throttled update approach expected early 2022 for all Enterprise ENS and consumer WSS installations that received update via V3 daily DAT updates, with no further action required.
