Major Geeks has a download link -- title says v. 2.0.0.176, but one of the links is a download from "author's site" so may be current: http://www.majorgeeks.com/files/details/kaspersky_anti_ransomware_tool_for_business.html
I'm not a business but I know you could download version 2 without filling out the form on their website before so I was hoping I could do that again for version 3.
Bummer. Are you using WIN 1083 (previewed as Redstone 4)?

I wonder how different KART 3.0 is compared with KFA 19, since the latter now integrates KSN, system watcher and network attack blocker (which KART relies on too)
