Since doing this we have found that Kasperky is blocking access to parts of Google Drive. We have not been able to work out how to stop this. We do not want to turn off scanning of Google Drive, but just allow the normal functionality.
The top part of the image shows how Google Drive looks when Kaspersky is running. The second part shows how it looks when we disable Kaspersky. Note that the File upload and Folder upload are greyed out and the option of Docs, Sheets and Slides are missing when Kaspersky is enabled.
Running Windows 10 1803 and we have tried this on a couple of computers.
