Windows 10: windows defender says problem app but no other info

Hello, I am on Windows 10 (2004) and Windows defender has had a yellow triangle warning on it a few days. It says, "Reputation-based protection...Potentially unwanted app found. Your device may perform poorly". When I click the Review button it says, "no recent actions". I don't want to click dismiss yet, or until I know everything is ok. I've scanned my laptop with McAfee and no problems found so I'm confused and decided to ask in here is anyone knew how to check out what Windows Defender is talking about? Thanks.

:)

  Start.
