Password protection for cloud folders - which virus program can do this?

I'm looking for a virus program that can also protect local cloud drives / folders with a password?

So for example I synchronize my Google Drive account on my laptop. Now I would like to protect this drive / folder with a password. Before I can open it, a password must be entered.

Does anyone know of a suitable virus program that can do this?

Why do you want a virus program? You get viruses for free.

Better an antivirus.

Seriously…
