I had read various reviews about bitdefender antivirus, so I decided to try it. This was the worst antivirus I have ever installed. It bogged down my computer to the point, where I could not even do a google search. It would take almost 20 minutes to boot up. There tech support kept having me install patches. It was one problem after another. Customer service would not issue me a refund even though their product does not work correctly. After 2 months I removed it from my computer, without any refund from the company. My computer is now running smoothly. read full review »
