is go to assist me a scam?

I received a phone call an the person claimed that I had been hacked and was in danger of losing critical data from my computer.  I was instructed to go to www .gotoassist . me and enter the key code to get help.  I did not follow the instructions, but went to Norton and had a full scan done on my supposedly infected computer.  No problems found by Norton.

I know that Gotoassist is a valid product for internal corporate support.  Have scammers got a hold of it and are using it for getting access to targeted computers?

Thanks
