Hi Antonio, suposing you're using at least virusscan 8.5 you can change settings under "VirusScan Enterprise Properties" section and set only "Product Version (VirusScan Enterprise)" less than 8.5. Here it should show only computers with a virusscan version under 8.5 (or without virusscan installed)
I built the following query and it works great for me:
Result Type: System Management -> Managed Systems
Chart: Single Group Summary Table
Labels are: Product Version (Agent) Values are: Number of Managed Systems
Columns: System Name, Engine Version (VirusScan Enterprise), IP Address, Tags, Last Communication, User Name
NOTE: I do the Engine Version to see if VSE ever appears, just in case I have a system with an earlier version even though no other versions except 8.8 should exist as we never used McAfee prior to 8.8.
Filter: Engine Version (VirusScan Enterprise) Less than 8.8
i did Managed State and Product Version (VirusScan Enterprise) is "less than" 8
Every answers has been very helpfully to me. I have changed my query and it´s more simple and efective.
Thank you so much
Good to hear
