I got Acronis True Image's real time protection through a promotion they did for users with WD drives last year -
Updates - Acronis True Image WD Edition Software 2020
I don't use Kaspersky, I use F-Secure SAFE, so I can't respond on that combination.
Aside from that, I used it for about a month, it did what it said on the tin well, with no massive affect on resources that I noticed. I went back to Marcium for my backups, if I wasn't a long time user of their products and was searching for an imaging software I'd not turn down Acronis True Image.
