Experiencing performance slowness by real time scan

Masato 4 months ago

Since 1 or 2 weeks ago, we started receiving reports from users that they were experiencing performance issues at launching / closing some applications on Windows servers.

We haven't changed any policies on the servers. If we disable real time scanning, the performance gets improved significantly. Is anyone else experiencing performance issues? Previously there was no such performance issue to open/close applications.

hi Maxim, Defender is not running on the servers. I opened a ticket with the support. As I checked the summary log, it simply takes too long to get the scan done even the files are not that big.

Is there any chance that Microsoft Defender got re-enabled (switched back into active mode) on these servers?
