Query: Trend Micro PC Cillin

Do not buy this product. If you feel you must, buy it from Trend Micro website or you will not have a warranty. I bought Trend Micro Internet Security Pro 2008 from Best Buy. It would lock up during a scan. After many attempts at getting service I ask for my money back. Trend Micro said they would not refund on a store product. Best Buy would not refund an opened product. So I am out $70.00. And they are still sending emails with no solution to the problem. I have ask them to stop sending emails but they are still comming. Worse than a virus.
