Greetings!
I recently was having a problem where my "Manage Applications" wasn't opening, and, after following the advice posted here, I thought it was solved, but I think my problem is a bit more complicated.
Once I started to use my computer today, I noticed that programs such as Steam and Ubisoft Connect would give connection errors specifically when my Kaspersky Internet Security was running (even if I clicked on "pause protection").
I created exceptions on both the firewall and the "manage applications" functions, but nothing worked.
I started to suspect that something was really wrong when one of the programs related to Steam was reported "moved or missing" (and it wasn't) when I tried to create an exception for it on "manage applications." I removed it from the list and re-added it, but once I clicked on "save", KIS crashed and restarted. This happened every time i tried to add this program.
I was considering reinstalling KIS, but decided to report this here first.
My OS is Windows 10, version 22H2 (comp. 19045.2604)
My Kaspersky Internet Security version is 21.3.10.391 (j)
