Defender Slowness Issue
Hi Team,
Developers have been experiencing extreme slowness lately. When we give an exclusion to C as in the below screenshot, It goes back to normal.
Exclude C is like saying don't touch C at all. As you know, this is not the correct solution. Is there anything we can optimize this situation for?Also, you find the Defender Performance Analyzer results in the attached files.
Thanks in advance for your support.

Hello,
yes, you are right that C:\ exclusion is very bad and should not be set.
Can your developers set more focused AV exclusions?
Our documentation would be here: https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/configure-exclusions-microsoft-defender-antivirus?view=o365-worldwide
If this doesn't help, I would recommend opening a support ticket.
Best,
HeikeThanks for your support. We have checked folder paths as detailed and created a new custom exclusion path for our case and it works well. HeikeRitter
