Are you seeing this on just a single machine or all your machines?
I can't reproduce the issue on any machines in my environment. The only permission that should be necessary for an account is that it's a member of the local administrators group on the system.
It may be an issue in WMI itself. You could try removing the AntimalwareInfectionStatus class and then recreating it.
To remove - From elevated PowerShell console:
Remove-WmiObject -Namespace "root\Microsoft\SecurityClient" -Class AntimalwareInfectionStatus
To recreate - From elevated command prompt:
mofcomp "C:\Program Files\Microsoft Security Client\AmStatusInstall.mof"
