Well, it turns out that the issue with my computer is much worse than I originally expected. Much, much worse. I've been meaning to come back here and post an update for several days now, but I've been really frustrated and discouraged, and I am having to use a Chromebook that I have used very little and am not as good at typing on, so I've been putting off posting an update.
With that stated....
.... apparently, my computer has been hit/attacked by something called Ransomware and most of the files on my 1TB hard drive (particularly, photos) are now encrypted and I can no longer access/view them. Each picture/file now has .ccc added to the end of the filename; which, apparently, is part of the encryption that has been done via the hacking.
This is extremely frustrating and disheartening, as I have literally over 500,000 photos on my hard drive, and, maybe, over a million pictures, and I'm not exaggerating. And while not all of them are actually personally-taken photos of my family or are of important memories, several thousand of them are. Evidently, the way this "ransomware" virus/hack/attack works is that it actually gets installed on your computer and then encrypts the files on your hard drive and makes them inaccessible to you. Then, several notepad files are created with this information and your computer's desktop background is actually changed to display the information about what happened to your files/why they are no longer viewable/accessible and you are given directions as to how you are supposed to contact the hackers and pay them to get the decryption key to regain access to your files. Supposedly, the amount required to get the decryption key is typically $500; and if you don't reply within 5 or 7 days, the hackers raise the amount to $1,000. And, possibly, if you don't reply within a week (or some amount of time), you may completely lose the opportunity to even possibly pay for the decryption key, as they claim that it will be destroyed, if you don't pay the ransom within a week or so.
I have been reading about this ransomware for several hours a day over the past few days and it seems like this is no joke and that there is literally no known way to decrypt the encryption that these hackers use to encrypt your photos/files and make them inaccessible to you. Apparently, the FBI knows about this type of ransomware hacking/virus and they are literally unable to decrypt/break the encryption that these hackers use. And the hackers ask you to contact them through the tor-browser, which is close to untraceable, so they are pretty much unable to be found and the hackers can actually communicate with you about this openly without having to worry about being traced. One person who was hacked even mentioned that he contacted some sort of support chat/help for the hackers through tor-browser and was able to negotiate the price back down to $500, after waiting too long and the decryption key ransom went up to $1,000.
By the way, according to the message that is visible on my computer's desktop background right now as I'm typing this, the encryption that is used by these hackers is RSA-2048 and they even include a link to the Wikipedia page for this type of encryption in the information. So, it seems as though this hacking and encryption is state of the art and, at this time, has no known way of being decrypted/broken. Also, some people have posted comments about paying the ransom (typically, the $500) and getting the decryption key and then being able to view/access their files again; but someone else pointed out that these posts could have been made by the hackers; and, to my knowledge, no one has actually credibly confirmed that paying the hackers the ransom will guarantee that you will get the decryption key or regain you access to your files. And some people have mentioned that they did actually pay the ransom, but did not get the key/did not actually regain access to their files. Not that I have $500 to pay the ransom right now; but I would like to know what the reality of the situation is and also inform myself about this as much as possible.
For the time being, I am in the process of moving all of the files from my computer's 1TB hard drive (over 900GB in total) over to an external hard drive, with the intention of reformatting my hard drive and at least being able to use my desktop computer again. And as someone mentioned in some post on some forum that I read through, the hope is that a decryption key/method will eventually be discovered and that the people who have been victims of this ransomeware will then be able to decrypt the encryption and have access to their files again, since they will have saved the encrypted files on an external hard drive (which is what I'm in the process if doing) and be able to access them later.
And in case anyone is curious, this is what the message being displayed on my desktop is right now:
"What happened to your files ?
All of your files were protected by a strong encryption with RSA-2048.
More information about the encryption keys using RSA-2048 can be found here:
http://en.wikipedia.org/wiki/RSA_(cryptosystem)
What does this mean ?
This means that the structure and data within your files have been irrevocably changed, you will not be able to work with them, read them or see them,
it is the same thing as losing them forever, but with our help, you can restore them.
How did this happen ?
Especially for you, on our server was generated the secret key pair RSA-2048 - public and private.
All your files were encrypted with the public key, which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.
What do I do ?
Alas, if you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed.
If you really value your data, then we suggest you do not waste valuable time searching for other solutions because they do not exist.
For more specific instructions, please visit your personal home page, there are a few different addresses pointing to your page below:"
OK, OP here again, and after that, there are some specific personalized links that I am supposed to go to, to be able to communicate with the hackers about the ransom that needs to be paid to be able to obtain the decryption key. As I mentioned, I do not have $500 to even be able to consider paying the ransom, even if I wanted to, so I have not even tried accessing any of these links.
Just before coming in here to post this a few minutes ago, I actually noticed a thread on another site where I also posted about this issue, that appears to be about what I believe is this exact ransomware hacking issue, so I'm going to also go post in that thread and see if I might be able to learn more about this and, hopefully, find out if there is a way to regain access to my files without having to risk paying the hackers the ransom they are asking for.
If someone has any ideas, suggestions or advice about this issue, or might be able to help me (and the many other victims of this awful hacking problem), please do help!!
And if you want to read up on this ransomware hacking stuff, just go to Google and search for "All of your files were protected by a strong encryption with RSA-2048" or even just "RSA-2048 encyption" and you will find several results with hundreds of posts by people who have dealt/are dealing with this extremely aggravating issue.
