Avamar-related 4624 events

I'm new to Avamar but have noticed some oddities during backup windows that I was hoping to better understand.  On devices with Avamar installed, I'm seeing a lot of 4624 events for multiple accounts using Authz as the Logon Procces and C:\Program Files\avs\bin\avtar.exe as the process name.  Is this normal behavior and is there anyway to stop this as it is filling my event logs.  Thank you all in advance!
