While the -2/-2 applies only to creatures that are on the battlefield as Malicious Malfunction resolves, the replacement effect applies to all creatures that turn, including ones that enter the battlefield after Malicious Malfunction resolves or noncreatures that become creatures after Malicious Malfunction resolves.
