DO NOT BUY THIS PRODUCT - IT DOES NOT WORK - YOU CANNOT OBTAIN A REFUND. I purchased Bitdefender Antivirus 2010. The software continually stops monitoring and the crashes my pc. Technical Support is unable to solve the problem. They suggested that I wipe out my entire system, reload windows and then their product. Of course, this is RIDICULOUS. I was well within 30-day refund policy stated on their website. I have made repeated telephone calls and emails requesting refund. To date, I have not heard from the company, after prolonged waits on the telephone, when I reach customer support I am told to wait an additional 24-48 hours for an email response. This has been going on for 8 days. This company is based on Romania -- my credit card company cannot help me due to international laws.
