ClearDefenderHistory
ClearDefenderHistory safely stops Windows Defender protections, clears the history files, and restarts protection.
ClearDefenderHistory allows users to temporarily stop Windows Defender's protection system to clear the history files. Once you've cleared your history files, ClearDefenderHistory will automatically restart Windows Defender's protection system to keep your computer safe from potential threats. With ClearDefenderHistory, you will not have to take ownership of Defender folders. This is a security hole because if you can delete those files, so can malware running as you.
Straightforward Deletion of Windows Defender History Files
The ClearDefenderHistory.bat file allows you to delete the Windows Defender history. It is a wrapper to a PowerShell script that creates a temporary scheduled task, which runs as TrustedInstaller to ensure the process is safe and trustworthy. Once the task is created, the script waits for completion or times out if it takes too long before removing it. If you don't have Administrator privileges, ClearDefenderHistory will prompt you to grant the necessary permissions to proceed.
Usage
To use ClearDefenderHistory, unpack the archive and double-click on ClearDefenderHistory.bat file to run it. Please note that you may get a UAC prompt without running it from an elevated console. Some users might need to right-click on the ClearDefenderHistory.bat file, select Properties, check Unblock, and click OK before proceeding.
ClearDefenderHistory is perfect for users who want to remove old detections under Protection history and stop seeing them; you can run the ClearDefenderHistory script. This can also fix an issue where Windows Defender keeps detecting a file as a virus even after the Defender team has updated the definitions and removed the detection.
