About Comodo LeakTest, 1st of all to test it You should move that tool to Low Restrict group in KIS2015 Application Control because it is moved to Trust group by default (KIS2015 trusts digitally signed applications by default, so You can untick that setting also), so no restrictions for that file when running, then change KIS2015 to Interactive Mode (untick "Perform recommended actions automatically"), and answering Block or Block Now in every warning (being a bit patient here ), You should get about 320/340 points.
"By the default settings" are a bit weak in my opinion, with a few tweaks You can get stronger protection in KIS, but maybe not so good/easy to manage for standard or newbies users
Even though, those missed 320 ->340 items, in Kaspersky Official Forum, Kaspersky developers said many years ago that this testing tool gives wrong results in some items related to KIS.
Regardless of what people say about KIS. Been using it for two years, and off and on not using an AV. and still haven't ever been infected with anything. Its a good AV. I stand behind KIS.
