That will not be sufficient. Remove the hard drive, trash it, and install a new one with a fresh Windows install.

Thanks for the input.

Can work files be saved first?

Neighbor says they have data on Google Drive. Should that be flushed too?

They are going to install Win 10. But the install is an upgrade. They should do a new install?

“... Remove the hard drive, trash it, and install a new one with a fresh Windows install” Very good advice.

I would add: Turn the old drive over to someone for analysis.

Isolate all other computers from the network, or buy a new router for a new network.

Change all passwords (email, FB, WiFi) from the updated unit.

Have any computers fully checked before joining network.

Consider whether the Ex’s comments meet the standard for bullying or child abuse in your state.

And while you're at it, drain your car battery and rinse it out several times, then fill it up with distilled water.....don't forget to check the muffler bearings and replace the stale air in the tires with fresh, bouncy air.
