Scam Alert: phone calls from 1-866-284-3547

Just a heads up.  

Received a phone call from guy with a foreign accent who told me that my Norton 360 had security issues.  I asked him who initiated this call and he just repeated that he wanted to help me solve my security issues.  I laughed and told him this sounded like a scam and he responded with a flurry of F bombs etc...   haha  Not sure how he knew I had Norton 360 but pretty sure he was trying to get access to my computer.
