Query: Stop working in like 3 days

A few days after I purchased Bit Defender and installed it, I began to get this error message...."BufferOver-run" Okay so basically after three days the software stopped working. I contacted the company and they basically attempted to help me but didn't follow thru. I realized that while they were taking their time getting to my issue my computer was at risk and I decided after 3 days of waiting to ask for a refund. I think the product allowed another virus on my computer.....this product is not worth it.
