I had what was the second most expensive Norton Virus scan and it turned out to be a joke. My laptop received a Trojan and the Norton Scan despite being faithfully updated every morning failed to stop the Trojan. On top of that when I visited the Norton site they wanted over $100 to purchase another product to remove the virus. This was something I was led to believe that the Virus Scan I had originally purchased was supposed to do.
It ended up costing me $165 to repair my laptop. I have sent Norton / Symantec several letters requesting a refund for the Norton scan that did not live up to its advertising without an answer. I also sent several letters stating that they should reimburse me for the cost of repairing my laptop, no answer to those requests either. They haven't sent an apology nor any other correspondence.
DO NOT BUY NORTON, IT DOESN'T WORK, IT SLOWS YOUR COMPUTER DOWN AND THE SERVICE IS NON-EXISTENT.
