What To Do If Windows Defender Keeps Saying Threats Found

Windows Defender is your Windows inbuilt defense against malicious threats. It scans your PC for malware, viruses, and other security threats. Despite being a decent antivirus for Windows, users have reported instances where Windows Security kept saying threats were found by popping up notifications stating PUP or other threats were found and quarantined. And it didn’t stop there and kept repeating the same notification every few minutes.

Why Windows Defender Keeps Saying Threats Are Found

In most cases, the identification is genuine if Windows Security identifies a file, process, folder, website, or anything else as a threat. It is best to take action and remove it. However, there are also times when Windows Defender/ Security may detect something malicious that might not be harmful. Such entities are known as false positives, and here are some reasons why such entities may arise – 

  • The threat was outside the database of threats that Windows Defender has. 
  • You removed a suspicious browser extension that had malware, but since the settings have not been changed, Windows Security has identified malware. 
  • A malicious file is already quarantined by another Antivirus software, and Windows Security has flagged off the same malware. 
  • Windows Defender identified its quarantined items or protection history as malware.
