I cant go back to an older version of Kaspersky, he automaticly update to the lastes one.
I disable for the moment the start up option of malwarebytes and run scan manually and then close it, because if they both run at the same time the internet connection fails, the web browsers fails, the windows explorer menu fails, and everything symple goes wrong.
I have reinstalled, and delete malwarebytes and kaspersky too, i have run separatly, and the problem is when the two of them are running from the beggining of the W10 system.
thank you to your respond and time for read my issues.
