This query identifies common processes run by ransomware malware to destroy volume shadow copies or clean free space on a drive to prevent a file from being recovered post-encryption. To reduce false positives, results are filtered to only actions taken when the initiating process was launched from a suspicious directory. If you don't mind false positives, consider removing the last where clause. Special thanks to Captain for additional inputs
