I had same issue. Kaspersky Lab Launcher was using CPU a lot and fan was running loudly. It is sure that this is leading to short life of laptop. This happened only when my laptop was running, but screen was off (10 min screen off) and when laptop was plugged in. I understood that this is some kind of background process. I have Kaspersky Total Security, open the main screen of Kaspersky, go to Scan->Background scan and turn off background scan. I'm not sure if this is wise solution for protection, but problem was solved.
Unfortunately its no longer possible to look/access support/incident tickets in (your) MyKaspersky account; Kaspersky shutdown the feature approximately nine months ago.

It is difficult to say whether Kaspersky or your provider has intervened.
You can check the reports to see if an action was recorded:
Main window 'More Tools'->Reports.
There you can check the reports of 'Anti-Spam' and 'Mail Anti-Virus'.
Ich nutze KIS seit vielen Jahren und denke nicht daran, das zu aendern. Meiner Erfahrung nach ist das ein sehr gutes Tool.
Ob das ein russischer Hersteller ist oder nicht, ist mir voellig egal. Hauptsache gut und bewaehrt.
