I've had nothing but trouble with this software. Since installing, Gmail has come to a screaching halt. I reported problem to BitDefender and their reply was that problem was to be fixed with an auto-update and I am still waiting for it after 90+ days. And auto-scan either does not work or it does not recognize when it scans because I continually received error that I have not scanned for malware in X number of days. I requested a refund but they said they only refund if within first 30 days. I explained I was waiting for their auto-update to fix Gmail problem and they did not reply. I've contacted Broward County, FL to assist me with getting my money back. Bottom line: Poor product, poor customer service. Don't buy it!
