Kaspersky antivirus program blocking iCloud push notifications on PC, how to fix

My spouse has an iPhone SE and I have those pictures backed up on iCloud for PC to enable editing if needed. Recently, popups have been occurring from my Kaspersky antivirus program stating that the iCloud notification service is being blocked due to an untrustworthy root certificate (see screenshots; the popup is first, below that is an expanded report). I've not been able to fix this to stop the popups. Has anyone had a similar experience and found a solution?
