[Kaspersky Safe Kids Recen Update blocking Youtube Comments, Gmail and Hangouts from loading even if the website is whitelisted]

First, thank you for detailed explanation.

Second, I cannot now replicate this issue as after clearing cache everything works. Mind you I haven’t found issues with ff.ksk.v2.scr.kaspersky-labs.com  after quick googling. There is a lot with ff.ksi.v2.scr.kaspersky-labs.com, but this is different server probably for Kaspersky Internet Security.

I guess this issue appears when there are old addresses injected in cache files, but they are not used by new version of Kaspersky product anymore. I think they should provide something like transient period when both function simultaneously.

Generally I think KSK is a little too rough around the edges for non IT users. Many people I know, that once used it, doesn’t anymore, because it stopped working for them at some point and they couldn’t figure how to fix it.

Which is a shame because it is a nice product.

Also, as a simple step you can try to clear browsing data All time on Chrome (with cookies).

This works. I had the same problem after Safe Kids update using Firefox on Windows 10 v1909 and clearing cache for Google sites helped.

Maybe you can pass to the developers that it hangs on “Waiting for ff.ksk.v2.scr.kaspersky-labs.com...”
