Some of my files were infected by ransomware a couple of years ago and I gave up trying to decrypt the infected files at that time, but I'm going to give it another try. (I did not have a local backup of my system to recover files from.)
At the time, I was not aware of ransomware, so I deleted the ransom note, not knowing what it was. I believe there may have also been an html or txt note for each infected file (in the same directory as the file), but I may be remembering this incorrectly.
The "ID Ransomware" site does not help me, because I no longer have the ransom note.
I do have some examples of infected files and the original *uninfected* files (which were backed up on a flash drive), but I don't have backups for all files obviously. Is there a site where I can upload an infected and uninfected file to determine the ransomware involved? If it can be identified, I want to try to find a decryptor for the files I don't have backed up (which is most of them, unfortunately).
