From Bitdefender Total Security :
The process E:\itch\gameslibrary\darkstork-onlinee\DarkStorySetup.exe manifests ransomware behavior and was blocked. Several files were encrypted by it and we couldn't automatically restored all of them. You can find the files to be restored below.
The file(s) that were encrypted by the installer:
iconcache_16.db from AppData\Local\Microsoft\Windows\Explorer directory
the file that was encrypted is thumbnail cache for 16x16 sized icons if I am understanding my results correctly.
