Kaspersky internet security is disabling internet when turning on the Mac

Dear Experts,

I have Kaspersky internet security 2019 (Original key) installed since a while on my MacPro.

And everytime I start my mac, there is no internet connection for a while (3/4/5 minutes) for all apps and web browsers.

Also, when I start my macbook, other devices that are connected to the same router are getting no internet connection, only wifi sign.

When I stop everything related to the kaspersky it works, but It is not the case since I need to have it opne to protect my laptop.

Anyone has any advice?

Thanks!
