Protection against randsomware

I love how the Icedrive virtual drive works. At the the same time, giving access to your cloud storage trough a transparant drive will make you also vulnarable to randsomware attacks. Is there any strategy using icedrive to prevent this? E.g. I do not store my credentials when accessing my NAS in order to prevent randomweware from accessing this.

I guess umounting the drive will do the trick.
Then mount for a limited time interval until sync is complete.
