Hello , sorry for delay. The issue was apparently linked to an issue with Windows 10 start. Usually it took long to have Windows starting when using laptop. But , I guess after an update , the start was very quick and Kaspersky issue disappeared.
I have latest version of kis and the same problem keep repeating from time to time : When kis start the exclamation mark appear and green logo become grey. Opening it I find corrupt licence information and update is running but at very very very low speed while internet speed is high , it take around 10 minutes. At the end of update , corrupt licence problem is resolved. Why is this licence problem happen and mostly why this specific update is so low while the normal one take just 1 minute . Can I get a normal start.
