Hello,
I do have Bitdefender Total Security 2017. Recently I renewed my subscription. I have it installed in a Vaio VCPEA37FL running Windows 7.
Some weeks ago I started with problems with Windows. It took a long time to log in. Between the welcome screen and the login screen, a black screen with the mouse arrow lasted for several minutes. Then, after loging in, Windows started with the "old style" task bar. A message window indicated that Windows could not connect to a service. A lock icon appeared momentary in the task bar notification area. Then, I logged off but it took several minutes to close the session. I try to find a solution over the internet and everything pointed out that the user profile was corrupted. I created a new administrator account, but it did not work. Same result. I tried to repair it. I got the message that msvcp140dll was not found. I repaired the distributable C. I ran the rootkit removal tools from different antivirus brands but nothing worked. Finally the system crashed. I did restore the computer to the factory settings (a pain because a lost some documents, software and had to reinstall everything). I did upgrade to Windows SP1, updated Internet Explorer 11, Google Chrome and then Bit Defender (before those updates I can not even open Bit Defender Central). After installing Bitdefender Total Security 2017, the bad sympthoms appeared again: long start up, black screen, old task bar, services not connecting, extreme long log off time.
I have read other threads and tried the solutions but none of them worked.
Please help!
