There is a discussion in this topic where you can ask questions and seek further assistance.
KeyBTC typically deletes all shadow copy snapshots
(created if System Restore was enabled) with vssadmin.exe
so that you cannot restore your files from before they had been encrypted using native Windows Previous Versions
or a program like Shadow Explorer
...but it never hurts to try in case the infection did not do what it was supposed to do. It is not uncommon for these infections to sometimes fail to properly delete Shadow Volume Copies.
Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in that topic discussion. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.
