Was I Hacked? DId Norton 360 Kill it? See the threat below

Hi, My N360 has been in use for many years and is current.  I received the following, below.  I think it's from Facebook.  I've changed the password in FB.  The message was tagged [Norton AntiSpam].  And I would usually delete them from my email in box.  But, just by chance, this caught my eye.  Has this clown screwed with my computer and data?  Or is it just a scam.  BTW, my Computer does Not have a camera. (See below).  If it is something that Norton can't kill?  What do I do?  I don't care about FB.  I want to keep my data safe. Everything is working correctly and to be sure I ran Norton Power Erase.  After that, I get just one error where, when I shut down Eudora 7.1 (Win7 64 bit) I get: Error accessing File: C:\program files (x690\qualcomm\edura\search\ism7c43.tmp  ACCESS Denied.  No such file or Dir Exits.

Can anyone help point me in the right direction.

Many Thanks in advance

Hello!

My nickname in darknet is dante21.
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 monitoring you for a long time.
So, your password from xxxx@xxxxxxx.com is xxxxxxxxxxxxx
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 $869 is quite a fair price to destroy the dirt I created.
Send the above amount on my BTC wallet (bitcoin): xxxxxxxxxxxxxxxxxxxxxxxx
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!
