What went wrong?
This issue only started occurring recently, my last successful download was the 16th of August.  This issue has started happening simultaneously across both my computers.  Both run Chrome dev.

Both computers run Sophos Home Anti-Virus, v1.3.1.  When a download fails, no alert is raised by the A/V and disabling on-access detection has no effect.  Downloading files in other browsers works as usual.

Disabling on-download scanning by using "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Attachments\ScanWithAntiVirus" (Set to 1 rather than 3) allows downloads to work as normal.

I think this is most likely a bug with how Chrome interacts with Sophos somehow.

Did this work before? Yes Unknown - Prior to the 16th of August

Chrome version: 70.0.3521.2  Channel: dev
OS Version: 10.0
Flash Version: 

Thanks for any work on this bug report :)
