It deals with the problem that when a computer deletes a file, it leaves empty physical space behind on the drive.

Experts: Windows Feature Can Be Used as Ransomware

Ransomware attackers could turn a key Windows security tool against the system, according to new research. The tactic could also evade leading security tools.
