Per LANDesk Doc:
"Using LANDesk Security Suite, you have the ability to manage Antivirus software from various vendors. This includes ensuring that a virus scanner is installed, that the realtime scanning engine is enabled, and that the antivirus pattern files are up to date...."
AV-105 specifically handles definition updates and that is all. The latest DAT gets downloaded from http://download.nai.com/products/licensed/superdat/english/intel/whatever.exe
The file is saved in the Patch repository as McAffeePattern.exe and is installed by running it with /S switch.
Engine/version updates is better handled using a Distribution Package and a query to detect outdated versions.
