Additional Microsoft Defender tools and services that provide security across various platforms and environments
Hello @Arthur ,
If Microsoft Defender repeatedly detects and blocks the same severe threat, it usually means that the source of the threat has not been fully removed and is being recreated after each detection.
We need more details and context to help.
I would assume that your question is about Windows Defender, this behavior can happen because of a malicious scheduled task, startup entry, browser extension, compromised application, or another infected device or network location reintroducing the malware.
