Can't upload images to post because of kaspersky

Hello,

I have the problem that I can’t upload images to a post and also not to revolution slider because kaspersky total security is blocking ist. I get the error message “dangerous URL was blocked”

thats the url: http://www.mywebsite.com/wp-admin/async-upload.php

However if I upload images in the media library (not when my post is open), I can do so without any problems.

Do you know what the reason for this could be?
