McAfee Anti-Virus Scanning Engine 5.8.00 (5800), 5.7.00 (5700)
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.

Intel Security 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. The old Engine reaches end of life six months after elective downloads begin.

5800 Anti-Virus Scanning Engine (current Engine)
The 5800 Anti-Malware Engine succeeds the current 5700 Engine and includes the following improvements:
Detection and Performance enhancements
  • Enhancements to Portable Document Format (PDF) format to improve exploit detection capabilities
  • Improved handling of Windows Executable format
  • Improved unpacking of .NET, Shockwave Flash, Visual Basic for Applications and generic unpacking improvements to detect more threats
  • Enhancements to live memory scanning in Windows for detecting and removing malicious processes, threads and files
  • Performance optimizations around initialization and scanning
Platform enhancements
  • New supported platforms: Windows 10, FreeBSD 10.x, Solaris 11 for SPARC

    NOTE: Windows 10 support is dependent upon the product using the scan engine. For example, both the 5700 and 5800 scan engines support Windows 10 with VirusScan Enterprise 8.8, provided patch 6 is also installed.

  • End of Life (EOL) platforms: IBM AIX 5.3, FreeBSD 7.x, Solaris 8 on SPARC and Linux Kernel 2.4
System requirements (disk space and memory)
  • At least 512 MB of free hard disk space
  • At least an additional 512 MB of free hard disk space reserved for temporary files
  • At least 512 MB of RAM for scanning operations (1024 MB recommended)
  • At least 1024 MB of RAM for updating operations

IMPORTANT:  VSE 8.7i endpoints must be using VSE 8.7i Patch 5 + Hotfix 1038699 or later to install the 5800 Anti-Malware Engine. The hotfix and Release notes are attached to this article (VSE87_P5_HF1038699.zip).
