In some instances Defender may need you to take some actions such as quarantining or removing the dangerous file or process. YES, Malwarebytes recommends people use safe mode to work perfectly. Observing Windows in safe mode enables you to narrow down the source of a problem, and can help you troubleshoot problems on your PC. If a problem doesn't happen in safe mode, this means that default settings and basic device drivers aren't causing the issue. If Defender finds malware on your device it'll block it, notify you, and try to remove the malware if it can. Safe mode starts Windows in a basic state, using a limited set of files and drivers.

Microsoft Defender's real-time anti-malware protection runs whenever your device is on, keeping an eye out for malicious activity. Here’s how: In Malwarebytes, open Settings, click the Security tab, and disable the Always register Malwarebytes in the Windows Security Center option.
