Press the Windows key + 'E' to open File Explorer.
Press Alt key, select Tools > Folder Options > View, then check Show hidden files, folders, and drives.
Navigate to the following location C:\\Program Files(x86)\EasyAntiCheat\ and delete the files:
Delete this file C:\\Program Files(x86)\EasyAntiCheat\EasyAntiCheat.sys
Delete this file C:\\Program Files(x86)\EasyAntiCheat\EasyAntiCheat.exe
