Scam mobile phone call so say from Norton Security

Just had a mobile phone call from a person saying they were from Norton Security and there was a problem with updates of anti virus they know my name and would I turn my Pc on and they would update my anti virus,(you dont catch me with this one) I have had a number of this type of calls lately the last one was from a area code for Bradford I rang my phone provider as I was suspicious of it they told me it was a car salesroom phone number (Norton Security car sales dont think so ) this mobile number I could not trace I also rang Norton in the past and asked if it was their policy to ring users of their product and was told they NEVER ring and it was a scam just as I thought so if any one gets a call like this report it to the appropriate authority
