You did the right thing.
Propely setting up good security nowadays is getting complicated. In fact, "managing" every computer and device on your home network can be a time-consuming challenge. Nowadays, you want as few computers as possible. Every computer is another security nightmare to deal with.
In general:
1. Try to keep your business computers and devices isolated from all other computers and devices on your home network.
2. Avoid, as much as possible, websites known to be associated with criminal activity, such as ****, gaming, travel, etc..
3. Be very careful clicking on links in emails. Unsubscribe to websites you don't absolutely need. Report spam.
4. Use a good VPN like NordVPN (#1) or Proton (#2 - but has in some cases stronger security than NordVPN, although it will significantly slow access to websites). Purchase and enable all of their extra threat protection.
5. Make sure your firewalls are always active. Sometimes, you will need to disable them - but then you have to make sure to reenable them ASAP.
6. Use 2FA on everything.
7. Use Yubi keys.
8. Use Google Authenticator.
9. Use full disk encryption. On Apple, this is easy -->. And in fact, using Apple computers will reduce the probability of hackers getting into your system, because they are not nearly as prevalent as Windows systems.
10. Get used to using strong passwords of 25+ characters. 1Password is excellent for this. Passwords made up of names are easy to use. 1Password will generate this for you and you can pick one if it suits you, otherwise have it generate another. In 1Password, you can store all kinds of other vital information as well.
11. Have encrypted backups. Apple has Time Machine which is absolutely excellent and well integrated. They also have "File Vault" for disk encryption, which is also excellent.
The above just scratches the surface.
Last but not least: Your bank accounts are the most precious resource to protect. Always keep an eye on them. If you are NOT good at security, you might consider logging on to them every day!
