Malware

Ive just bought a new MacBook and transferred everything over from old MacBook and now keep getting a message popup saying "“KreberisecDaemon” will damage your computer." Report malware to Apple to protect other users.

Options are show in finder or OK.

Ive searched for it in finder, found, deleted and emptied trash.

Message popup continually returns and i have to hit OK to do anything else..... how do i get rid of malware if its still there and the popup??
