My Total Security 2017 kept turning it self off so I phoned customer services and got put through to India who advised me to do a repair in the windows 7 control panel which I did . At the end of the repair, the screen advised me to reboot which I did only to get a major system failure. No windows boot up nothing . I lost everything in my computer all software and data .This cost me £200 to rebuild my business computer and all Bitdefender offered me was six months extended subscription . What has happened to them the quality of Bitdefnder has gone down the pan . I believe that Total Security no longer goes in for extensive testing for bugs any more in a rush to get on the shelves . I will never be buying it again.
