I've looked at this post but no solution is listed: https://community.mcafee.com/message/161954
It's title, "Multiple entries for the same PC" - I'm having the same issue on a couple of systems (Servers).
We have uninstalled and reinstalled the agent but the problem persists.
Each product installed is showing as follows:
McAfee Agent, McAfee Agent 126.96.36.1992, VirusScan Enterprise, VirusScan Enterprise 188.8.131.520, etc... for all the installed products.
Any suggestions would be appreciated.
