Hello m g, 
 Thank you for reaching out to the Sophos Community. 
 I would like to ask what version of Sophos AV you&rsquo;re running at this time? You can find this information by opening the "Sophos Endpoint Self Help" tool and looking under the "System" tab. Do you know if the issue only started up recently, or have similar symptoms been present in the past? 
 As an initial step, you can try enrolling the affected device in the "Early Access Program" for macOS. The EAP release includes some changes to the way scanning occurs. Mainly the scanning of network traffic. 
 In previous versions of Sophos AV for macOS, all network traffic generated would need to pass through the "NetTransparentProxy" which would become inundated with requests causing perceived slowdowns to web browsing and general network interactions. With the EAP version, network traffic generated from non-browser applications will be handled differently. 
 Let me know if this helps.
