So I got hacked installing a program. The program wasn't working so I uninstalled it right away.

I noticed all of my game accounts getting their passwords changed and realized that I probably got hacked and I changed all my passwords.

A day later, I reinstalled my OS to get the hacker out.

Now its been a week and I just got an email from the hacker. He sent me all my passwords to all my emails. With the passwords he sent me a screenshot of me deleting the program and a letter.

In the letter was from the day of the hack 12.20.2024 and he claims he has full control of my computer and he says he has some curious videos of me.

By now I have already reinstalled my OS, and changed all my passwords.

Can the hacker really do anything?
