No, I mean here, which one is better, default is scanned by format but i changed it to all files! I don't know which one is good!

Some modules were changed of place, some modules were renamed, for example, I'm testing Kaspersky Plus version:
  • Web Anti-Virus now it is called -> Safe Browsing:

  • There is no more Applications Control -> Intrusion Prevention:

  • No More Tools settings, all the settings/modules there were re-located to different sections (in Privacy and Performance sections):

  • New TimeLine feature (probably copying BD's one 😁):

And probably some additional changes I can't remember now 😁, just download and check it, for now this 21.5 it's a bit unstable, upcoming a new beta build soon, probably this upcoming week...
The overall UI looks really good on this!

I received an update from the previous RC build to the 384 build. A screen popped up requesting a reboot, all the while KIS was disabled and MS Defender was reenabled. Upon reboot, the installer popped up and installed the new version. Overall I think they should get rid of the gaps in protection, I don't like that KIS was uninstalled automatically and effectively left me without protection until I rebooted.
Settings seem to have carried over without issues.

It can be done on reboot as other AV like ESET do. New installer places new files, schedules them for replacement on next product start/system reboot and voila, upgrade done with no interruption.

I would say not for a little while because they are still displaying the previous line on their main site, there are links to switch now when when you try to click it still redirects you to the old products.
I just tried it again still the same it directs to 21.3 the old products
