Just got off the phone with the Kaspersky customer service,, alias Kaspersky morons. Their new theory is "Kaspersky does not support Linux". I tried to explain that this is not linux but a feature of Windows, it's just like any other app in Windows. They don't want to hear that. I have used Kaspersky for at least 8 years now, and this is the first time I decided to rely on their customer support. It is surprising how stupid these people can be. I wish I knew about this thread 30 minutes ago to show them how any Windows user in this thread is smarter than their best techs on the phone. Btw, I have the same identical symptoms, Ubuntu works only if I completely exit Kaspersky, disabling all Kaspersky components does not work.
