And I found that it only happen when I open a game call "mobile suit gundam online"
this game name "機動戦士ガンダムオンライン - 1.0.0.5" in the report.
when I start this game, the progress of Kaspersky Free cost 15-30% form cpu, until I close the game.
Also I have tested with other games(e.g.FF14) and don't found the same issue.
