Windows Defender Internal Conflict Causing a Slowing System

Windows Defender protects your computer in real time.

Windows Defender protects your computer against pop-ups, slow performance and other security threats. If you are getting an "Internal Conflict" in the program, you can take several steps to troubleshoot the problem. If none of your solutions work, you can disable the application to speed up your computer's performance.

Update Computer Anti-Virus Programs

Update your computer's virus definitions. Open your virus protection program, such as Norton Anti-Virus and click "Update" to download the newest definitions. If the "Internal Error" appears on your computer as pop-up window, the problem may actually be a virus on your computer. Windows Defender may not be the culprit, as this error is common to many non-Windows Defender related viruses.

Install Windows Defender Updates

Update Windows Defender. Click "Start," "Programs," and click "Windows Defender." Click "Check for Updates Now." You may need an update to the program, which could solve the problem.

Disable Some Forms of Real Time Protection

Windows Defender protects several aspects of your computer in real time. Disable one of the forms of protection to see if the problem disappears. Open Windows Defender, click "Tools," "Options," and locate "Real Time Protection." Review and remove the check boxes for areas you wish to remove from automatic protection.

Disable Windows Defender

If you cannot solve the problem, the best solution is to disable Windows Defender, but make sure that you have active anti-virus and anti-malware programs running on your computer. Disabling the application will end the slowing of your system. Click "Start," "Run" and enter "services.msc". Double click on "Windows Defender" change the startup type to "Disabled." Then. Click "Start," "Run," and enter msconfig. Click "Startup" and remove the check in the box for Windows Defender. Click "OK."
