Do I need to reinstall Bitdefender or is there a different problem?

I downloaded and installed Bitdefender Total Security a couple months ago and didn't have any issues with it. Recently I scanned with the rescue environment as well as use the one click optimizer due to persistent high disk usage and slow performance (which I suspected was either due to a resilient threat or errors). No threats were found and several hundred registry errors were fixed, but afterward, now I keep getting the bad image error pop-up as shown in the attached screenshot. Does anyone know what is wrong? Do I have to reinstall Bitdefender or is it possible there is a resilient hidden threat on my machine that has attacked and compromised Bitdefender? Thank you.

  • Hi @MichaelBA,

    The repair process described by @Gjoksi at step 1 should fix this error. Try it out and let us know how it goes.

    In regard to high disk usage and system performance, in the event this behavior persists on your devices, check the below article for possible causes and remediation recommendations:

    To ensure that Bitdefender is installed correctly and functioning properly, you can try reinstalling it. Uninstall Bitdefender from your system and then download the latest version from the official Bitdefender website. Install it again and check if the "bad image" error persists. Make sure that you have the latest updates for Bitdefender Total Security installed. Updates often include bug fixes and improvements that can resolve issues like the "bad image" error. Open the Bitdefender application and look for an update option or check for updates within the settings. The "bad image" error can sometimes occur due to corrupted system files. You can use the System File Checker tool to scan and repair any corrupted files. Open a Command Prompt window as an administrator and run the command "sfc /scannow". Allow the scan to complete, and if any issues are found, the tool will attempt to repair them.
