Boite mail Outlook hacked

Bonjour,
Ce matin en ouvrant ma boite mail outlook, deux compléments étaient bloqués (par outlook et Kaspersky), et un message d'un de mes contact m'avertissant qu'il recevait depuis deux jours pleins de spam avec mon nom et il y avait également un mail envoyé par moi même avec le message suivant:

Hello marie.XX@XX

My nickname in darknet is ive42.
I'll begin by saying that I hacked this mailbox (please look on 'from' in your header) more than six months ago, through it I infected your operating system with a virus (trojan) created by me and have been monitoring you for a long time.

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.

I have access to all your accounts, social networks, email, browsing history.
Accordingly, I have the data of all your contacts, files from your computer, photos and videos.

I was most struck by the intimate content sites that you occasionally visit.
You have a very wild imagination, I tell you!

During your pastime and entertainment there, I took screenshot through the camera of your device, synchronizing with what you are watching.
Oh my god! You are so funny and excited!

I think that you do not want all your contacts to get these files, right?
If you are of the same opinion, then I think that $500 is quite a fair price to destroy the dirt I created.

Send the above amount on my bitcoin wallet: 1MN7A7QqQaAVoxV4zdjdrnEHXmjhzcQ4Bq
As soon as the above amount is received, I guarantee that the data will be deleted, I do not need it.

Otherwise, these files and history of visiting sites will get all your contacts from your device.
Also, I'll send to everyone your contact access to your email and access logs, I have carefully saved it!

Since reading this letter you have 48 hours!
After your reading this message, I'll receive an automatic notification that you have seen the letter.

I hope I taught you a good lesson.
Do not be so nonchalant, please visit only to proven resources, and don't enter your passwords anywhere!
Good luck!

Si une personne pouvait m'aider, je ne sais pas comment agir.
Merci d'avance,

Marie
