KES Processing Error on Google Drive shares [KES for Windows]

Problem Description, Symptoms & Impact

KES File Threat Protection sometimes can't check Microsoft office documents from mounted Google Drive shares, therefore generating Processing error events. This issue is caused by an incompatibility between Google Drive VFS driver and KES. There are no plans on making KES compatible with Google Drive.

Workaround & Solution

As a workaround, add files with Office extensions stored on the share to exclusions, this shouldn't lower protection, because Office creates a temporary copy of a document when it is opened, which will not be in the exclusion scope and will still be checked. Example for .xlsx files: Path\to\google\drive\folder\*.xlsx, where Path\to\google\drive\folder is replaced with an actual path.
