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.
