Abstract
Disclosed are systems and methods for protecting a computer system from ransomware and malware by copying and backing up files using a volume filter. A storage stack of the computer system includes a file protector driver and a volume filter driver. The file protector driver monitors for potentially dangerous actions to the system's files. The volume filter driver tracks any requested changes to files on a block level, and makes backup copies of the modified blocks when the blocks change on a block level of the storage device.
