To add to this, here’s what I would do personally:

For disinfecting devices, it’s a process:

1. Isolate the device, remove network cards if possible.
2. Try to find out what kind of malware it is? Is it isolated to the OS? If it’s infecting device firmware I’d just replace the whole device, otherwise move to next step.
3. Copy essential data onto a removeable drive (USB)
4. Wipe the drive and re-install the OS fresh.
5. Full content malware scan of all files on the USB.
6. Copy files back onto fresh OS.

Some additional things to do:

1. Change relevant credentials.
2. Enable Multi-Factor Authentication (MFA) wherever offered.
3. If you’re in the US and believe that financial info was compromised (SSN, bank passwords, etc.), freeze your credit and file 1 year fraud alerts with all major consumer reporting companies (Equifax, Transunion, Experian, etc.). This is free and quick as required by law.
