I am using KIS 2019. Blocking malicious unsafe connections is great. However, sometimes I need to review them. When I type some keywords to sort out the application (with red square), they appear just a couple of seconds then DISSAPEAR. Same things happened when I review quarantined files. This is annoying, the previous KIS have no similar issues. The product that we purchased should work as we want.
Another thing is, I am working with Python, all module packages should be downloaded and installed from network source, KIS blocked them all. To continue, I have to disable KIS, let my PC vulnerable to finish updating those modules. I think KIS developer should figure it sooner or later.
