Yes, I performed this test, even with the antivirus disabled, it still continues to show the same error, preventing me from downloading.

I also updated my Windows and performed the updates notebook dell, but it didn't solve the issue.

The only solution was to change this key

Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Attachments

    I have the same issue. Changing registry key didn't help. I cant download any file with chrome and edge. Firefox works.
    I tried to login with different account i got same behavior.

      This worked for me

      It is similar to the often mentioned 'Current user" registry change, but not the same.

      Here you change the ScanWithAntivirus setting in HKEY_LOCAL_MACHINE from 3 to 1

        We are having the same exact issue here. I have several computers that started doing this, earlier this week.  I even went so far as to remove the AV completely, I did the registry hack, I change the settings in attachment manager. Nothing seems to work.

        I have run virus scans, malware scans, changed browser settings, (although it appears to be all browsers are affected) 

        I am guessing it was a Windows update that may have caused the issue. I am at a total loss as to how to correct the issue. It is a big deal as we connect to a citrix platform, and it requires a download to run, every time we connect, but since it is blocked as a virus, with the same exact screen that is shown above, these computers cannot connect.
