I sold my laptop computer last Oct. The other night on one of my business computers an intrusion alert popped up by Norton that someone was trying to intrude into the computer.

Another alert popped up on the other computer about five minutes later. The name Norton shows for the Intruder is the name of my old laptop.

Last night Norton blocked the message 'filetransfer.msg.yahoo.com/notifyft'. The name of the computer is my old laptop that was sold to this person.

Is this person trying to gain access to my business computers, and are they trying to transfer files?
