The main reason for this problem is that the BitDefender driver is broken or not working correctly, even if you already removed BitDefender from your computer. Other reasons include problems with other drivers or computer memory issues. In this guide, we’ll walk you step-by-step through several effective methods to resolve this issue. Let’s get started!
1. Use System Restore
System Restore allows you to revert your computer’s configuration and registry settings to a previous point in time when everything was working correctly. Windows 10 usually creates restore points automatically, especially before significant changes like installing or uninstalling critical programs. You can also create restore points manually, but in most cases, Windows 10 has you covered. A common solution to fix the bddci.sys Blue Screen error is to use System Restore and return your PC to a previous working state. If System Restore doesn’t solve your issue, move on to the next method below.
2. Uninstall BitDefender Antivirus (If Applicable)
In many cases, this error has been linked to the latest updates of the BitDefender antivirus program. Most users have fixed the bddci.sys error by uninstalling BitDefender, so if you’re currently using it, try the steps below:
3. Rename the Sys File
If you’re not currently using BitDefender, but had it installed in the past, leftovers from the program might still be causing problems. Renaming the bddci.sys file can stop Windows from loading it at startup, which often resolves the issue. You can also try renaming the bddci.sys file located in C:\Program Files\Bitdefender Antivirus Free\web\ if BitDefender was installed on your system.
4. Uninstall Windows Update
If you began experiencing this problem after a recent Windows update, it’s possible the update introduced a bug or conflict causing the Blue Screen error.
5. Run SFC and DISM Scans
Sometimes, the bddci.sys Blue Screen error can appear if your system files are damaged or corrupt. You can often fix these problems with two built-in Windows tools: SFC (System File Checker) and DISM (Deployment Image Servicing and Management). SFC checks for and replaces corrupted files with healthy versions, using a locally stored cache. DISM can further repair system images and requires an active Internet connection.
6. Delete Bddci.sys File
If none of the above methods work, you can try deleting the bddci.sys file directly. We’ll do this using Command Prompt in the Windows Recovery Environment (WinRE). The WinRE can help troubleshoot, recover, and fix startup issues. Exit the Windows Recovery Environment. Hopefully, this will finally resolve the bddci.sys Blue Screen error for you.
