I have a little problem. Three days ago, a firewall alert popped informing of a virus. On Sunday, I cleaned up a part of my pc and found out a number of my files had been encrypted. At no time have I found a message in the desktop about the ransomware or txt indicating me to pay to recover them.
I don't know whether it's been because of me cleaning up some files, that the process could not complete and the encryption of the files did not get to the end of the process. The files have not been renamed, they have their original name and extension. The only thing I could find was a file in quarentine named "derris.dll".
I've been reading about this and in this forum and it seems it can be the "ransomware pclock", but I'm not sure.
I've also tried to verify the type of ransomware (ID) in this website - https://id-ransomware.malwarehunterteam.com/ - but there were no coincidences for it.
I've been trying with multiple decrypters but I haven't been successfull.
Here you have an encrypted file and the original file before the encryption.
Thank you in advance for your help!
