Sophos FileScanner "SophosFileScanner.exe" spiking Up To 40% CPU Usage

Hello Sophos Community, 

I manage the Sophos Endpoint Antivirus Solution + Sophos Centrale. We are currently using the Sophos File Scanner Version The CPU Usage spikes drastically to 40% in a ten minunte interval. Do you know any tricks to reduce the needed ressource for live file scanning? Everyone of us got Surfaces with a powerful CPU (Intel(R) Core(TM) i7-1065G7 CPU @ Base 1.30 GHz).

  • I've enabled the SFS logging on a few clients and told my colleagues to write down the time when the problem occurs. I am going to wait a couple of days and will analyze the logs after. I've checked the scheduled scan config on my endpoints. We full scan the devices every wednesday on 09:00 AM, every device got about 300GB internal disk capacity to scan. I don't think the scheduled scans are the problem, because I can't imagine scanning round about 300 GB would take more than one day. I'll keep you updated. Thanks for your help! Slight smile
