Windows 10: How do I prevent hackers?

I keep getting charges from Microsoft Store on 2 different banks and 4 different accounts. I close the card and get a new one and then they hack it again; including the one for my 9 year old grandson's savings account which we don't use for anything other than savings. How do I stop these evil hackers?

HACKER PROBLEM

1. You cannot restore *restore points* that have been deleted

2. You have to prove you have a Hacker first then see...

Payback time! How to catch a hacker

3. To prevent you need to figure out how the person got into your system. What kind of protection do you have? Part of keeping intruders out has to do with the kind of protection you have.

And, it may not be a hacker at all it might be a virus or Trojan or just malware. I would suggest downloading and scanning with...

Cyber Security Software & Anti-Malware | Malwarebytes

Then make sure you Anti-Virus is up to date. I would also suggest after you scan you change your passwords, however, again... after you scan with MalwareBytes. If none of that works then you need to take your PC to reputable shop and let them clean it
for you.
