Thanks for your concern in helping me. I would uninstall Kaspersky and try to do it as you suggested, of course, no problem at all, but as I received the message below from Malwarebytes support today, it's no longer necessary I believe.
"Hi Uligyn,
Thank you for contacting us at Malwarebytes support. My name is Breaux, and I will be to happy assist on ticket # 3079358.
I am sorry but your license expired in December of 2019 when it failed to renew. In March you paid to renew the expired license but unfortunately, it remained expired. When a license is due for renewal you only have 30 days to save and renew. If not done in time the license will expire. Once expired it cannot be renewed again.
The billing system should not have allowed a renewal that many months later and issued you a new license.I apologize for this confusion and inconvenience. I have refunded your subscription reference # 115958831. Please allow 5-7 business days to fully process. Please note that you will also get a confirmation email from our e-commerce partner when the refund is processed.
Please purchase a new subscription from malwarebytes.com/pricing when you are ready.

Thank you all, very much, for helping me.
My kindly best regards,
