Thank you. I only posted here because it was the only post I've found with a very similar scenario and I couldn't get any useful update/response from Kaspersky support so I gave up. And just for the record, in my case, removing the Kaspersky Firefox browser extension fixed the issue.

You can change Your GUI in Spanish into English with SHIFT + F12 and revert to Spanish with SHIFT + F5, in every system start, being K. GUI open with main the focus. What do you mean, other languages in K. Support or?

I have this problem. I live in Spain and if I buy kaspersky here it's in Spanish....obviously. But I had to contact chat to get help changing it to English. Does anyone know if they have added other languages yet?

That's strange behavior. I ran a test using the network agent utility that sends the heartbeat, and I always get a return of 1460 (considering 20 bytes of the IPv4 and TCP header). Well, glad you found the solution.

Moin! Ich habe ein Problem mit Kaspersky Plus. Wenn ich den Netzwerkzugriff für ein Programm (in diesem Fall Corel) verbiete oder Benutzer fragen in den Regeln auswähle, passiert nichts, die Einstellung wird ignoriert und ich darf mir einigen Tage später wieder die Werbung anschauen. Was mache ich falsch? Hat da jemand einen Tipp für mich was ich machen kann ohne das Programm zu deinstallieren?

1. VPN IP ranges are known VPN providers use big blocks of IP addresses. Websites, advertisers, and security companies buy or scrape lists of these IP ranges. If your IP matches one of those? Ding ding ding, they tag it as VPN. 2. Too many users, same IP If hundreds or thousands of people appear to be using the same IP at the same time, that’s not a normal residential behavior. Normal households don’t share their internet with 2,000 strangers. 3. Traffic patterns look “non-residential” VPN nodes usually sit in: data centers cloud hosting providers server farms Websites see those IPs and go: “Hmm… that looks like a server, not a house.” 4. Missing fingerprints Real residential ISPs have: predictable DNS typical latency ranges expected routing patterns VPNs break that pattern. Even without spying, websites just notice the weirdness. 5. Enhanced fingerprinting Some sites combine: IP reputation databases browser fingerprinting TLS/SSL fingerprinting behavior analytics So even if the IP is clean, the overall signature still screams: “I’m coming through a proxy.” So yes, VPNs hide who you are, but not that you’re using one. Think of it like wearing a mask in public… People don’t know it’s you, but they definitely know you’re masked.

I was also having this issue, uninstalled Yahoo Finance App and discontinued Samsung Internet. Not sure exactly what discontinued means. Language from my phone. Can't figure out which file it is to attach it. Kaspersky does not quarantine it, only alerts me and I block it. The Samsung Internet is still there. Cannot remove it.
