Antimalware Service Executable是Windows Defender用来运行其服务的后台进程。导致CPU 使用^{(High CPU Usage)}率高的进程是MsMpEng.exe（反恶意软件服务可执行文件^{(Antimalware Service Executable)}），您可能已经通过任务管理器^{(Task Manager)}检查过它。现在问题是由实时^(Real-time)保护引起的，它会在系统唤醒或空闲时不断扫描您的文件。现在杀毒软件应该做实时保护，但它不应该连续扫描所有系统文件；相反，它应该只偶尔进行一次完整的系统扫描。

这个问题可以通过禁用全系统扫描来解决，它应该设置为只在一段时间内扫描整个系统。它不会影响实时保护，例如每当您下载文件或在系统中放置笔式驱动器时；Windows Defender将在允许您访问文件之前扫描所有新文件。这对你们双方来说都是双赢的，因为实时保护将保持原样，您可以在必要时运行完整的系统扫描，从而使您的系统资源处于空闲状态。够^(Enough)了，让我们看看如何实际修复MsMpEng.exe高CPU使用率。
