IIS requests slowed down

[Nagy Zoltán]

After the last version update, making any requests to locally installed MS IIS webserver unbeliebable slowed down, sometimes it takes 30-40 seconds or more.
This is a developer windows workstation, we use IIS for testing new web development locally.
If we turn off Kaspersky protection the issue disappears.
Kaspersky Small Office Security 21.24.8.522
My worskstation is a Windows 11 Professional x64 Build 26200
IIs version: 10.0
On another workstation with Windows 10 Pro we experienced the same problem.
Non local requests works well.
I tried turn off only safe browsing component, but it does not solve the error.

Welcome to Kaspersky Community.

 

How do You make those requests? Via browser or?

[Nagy Zoltán]

Hi,

Anyway. Via browser (navigate or refresh), xmlHttp request or using fetch api from javascript code, doesn't matter how, the result is the same.

Ok, We can try to create an exclusion of localhost in Intrusion Prevention -> Manage Applications, for the browser, similar to this, I took FireFox of my main browser, as example:

Thank you very much!
