It’s worse than rape. We only use our desktops to access the internet and to store software which we then enter data in and transmit. We set all our computers to no downloads without asking and then when each person goes home for the day they unhook their computer from the internet. Not much else I know to do. Hopefully that will help some.
The computers with all our data are laptops and they aren’t even connected to the internet. Takes a little more time for everyone to do their work but at least we know client’s and patient’s information cannot be accessed that way.

Here is a suggestion for you. A legendary programmer named Steve Gibson has written a utility to prevent unwanted upgrades to Windows 10. It will also erase any Windows 10 install files that have been secretly downloaded to your computer before the unwanted upgrade happens. Gibson used to write commercial utility programs such as the disk utility named SpinRite. Most of the software he writes now is free to the world, as this is.
