I got a reply from support: Dear Customer, Thank you for contacting Kaspersky technical support. This key combination launches the Kaspersky on-screen keyboard. Unfortunately, you cannot change the key combination for the on-screen keyboard, but you are welcome to disable this function by going to the Kaspersky application under: Kaspersky main window -> Gear bottom left -> Advanced -> uncheck "Open on-screen keyboard with Ctrl+Shift+Alt+P" and save the setting. Thanks a lot. However, this option does not exist (the only option is hardware virtualisiation): I was not able to respond in time due to the holidays and the ticket was closed. So, I have reopened another ticket and will update you with their response.
