Hello!
I'm is very good coder.
I am known by my nickname nikolaus94.
I hacked this mailbox more than six months ago,
through it I infected your operating system with a virus (trojan)
created by me and have been spying for you a very long time.
I understand it is hard to believe, but you can check it yourself.
I'm sent this e-mail from your account. Try it yourself.
Even if you changed the password after that - it does not matter,
my virus intercepted all the caching data on your computer
and automatically saved access for me.email sender data

What now?
1. Start using Firefox and two addons:
2. Install KeePassXC and change all your repeating pass-phrases to at least 20 characters long. Make a backup.
3. Star making backups of the most important data.
External HD, your own OwnCloud is a good solution.
