As such, you should uninstall the app and remove its leftovers from your PC. Then download the BitDefender installer and run it on your computer.

1. Open the elevated version of your command prompt (look the instructions up in the previous fix).

Close the command prompt window and restart your PC. Then check if the manoeuvre above has resolved your issue.

And yet no luck? That is a symptom that your Windows Registry needs a comprehensive checkup. If you are an advanced user, you can perform it yourself by examining the system registry and removing suspicious or damaged entries from it. If you are unwilling to do that, you are free to hire a technician and pay them to get your registry cleaned. But you might as well use reliable freeware such as Auslogics Registry Cleaner to save yourself a lot of time, money, and effort.
