Caller ID says - NAME NOT FOUND

Name was unavailable.  Tried making me remove some file in my computer they claimed was dangerous, but they provided little information about themselves which lead me to believe they were trying to scam me or even open me up to hackers. Their services sucked too.  Last thing they said was, "F*** off"

Just got called,callerID was 'New York Call'.Left no message,except a voice that sounded like they were going to start talking,but stopped when they realized they would be talking to an answering machine!!Like Kimberly above, I've gotten calls about my computer having viruses and errors,wanting me to turn on the computer immediately!etc.Was based in New York,and caller had heavy mid-east or Asian type accent.
