So I'm having issues related to connection with some apps, especially the apps from Microsoft and Microsoft store like Microsoft 365, WhatsApp and also including some game launcher like Hoyoplay & Epic Games launcher, all of those apps can't connect to the internet recently. I figured out what causing the issue was monitoring of port 433 on my KIS which is it's not a problem before but now i need to disable it in order for the apps to be working again. any solution of this as i'm having concern regarding disabling the monitoring of 443 port would cause any security risks in the future? my KIS current version: 21.3.10.391 (m) Thanks in advance.

My KIS has been updated and is now called Kaspersky Standard. When I try to enter a new activation code for KIS, I get an error message saying that the code is blocked. What should I do? Why might the code be blocked? I just opened the box with that code today. Kaspersky Internet Security for 3 devices. One-year license

Regarding KIS and KTS, is there a maximum period within which the activation code must be activated? For example, does the activation code become invalid if it is not activated within 10 years? Thanks.

My subscription was for years been taken care by 2Checkout and had no problems. I tried updating my subscription and for the first time I'm only being allowed to pay Nexway. I updated and paid the subscription, and haven't received a single confirmation. I think some kind of massive scam is going on with Kaspersky/Nexway and they first charge the customer, then upon receiving the payment disappear. Zero customer support replies from Nexway. All evidence available and I will be filing a report for 2Checkout/Nexway

Hello everyone. I need help figuring out what's going on with my Instagram account. A few days ago my main Instagram account was disabled. I sent the selfie verification and my official document and it was successfully reactivated, but then yesterday it was disabled again and I still haven't done the verification out of fear, and now I'll explain why... I used several secondary accounts to like my posts. Because I liked to post content for informational purposes, but my friends made fun of me because no one liked me and even though my page grew and then real users started liking me, I never gave up the habit. I completely stopped doing this after the first disable, a…

Problem description: Hello Kaspersky Support Team, I would like to report a critical issue with Kaspersky Internet Security on Windows 11. Since yesterday, Chromium-based browsers have stopped browsing the Internet correctly while Kaspersky is active. The issue affects both Google Chrome and Brave. Windows shows that my laptop is connected to the Internet and has Internet access, but when I try to open websites from these browsers, the pages either keep loading indefinitely or fail with the following error: ERR_CONNECTION_RESET The browser console also shows multiple connection-related errors, such as: net::ERR_CONNECTION_RESET The clear…

Hi there from Stripe, Since approximately mid-April 2026, Kaspersky's HTTPS traffic scanning/injection is breaking Stripe.js payment iframes on merchant websites. The MITM proxy alters iframe contents, which triggers Content Security Policy violations and causes browsers to block the payment frame entirely. ▎ Impact: End users with Kaspersky installed cannot complete payments on sites using Stripe. Disabling only the browser extension does not help — the full Kaspersky application must be disabled. ▎ Root cause: Kaspersky's web protection rewrites or injects content into cross-origin iframes served from js.stripe.com / *.stripe.com, violating the CSP he…

English Hello, since i updated the macbook to Sonoma, every two days or so, when i start the computer, and i go into Safari, I get the error: "A secure connection could not be established." This is because Kaspersky does not start correctly, and the 'full hard drive access' privilege is cancelled, and I have to give it access again... Why is this privilege canceled automatically? I have uninstalled Kaspersky, and reinstalled it, and the error still occurs. How can I fix it permanently? Thank you. Castellano Buenas, desde que actualicé el macbook a Sonoma, cada dos días o así, cuando inicio el ordenador, y me meto en Safari, me sale el error de: "No se pudo …

Hello everyone, I am facing a severe issue with Kaspersky's Firewall where it completely blocks or heavily throttles local P2P connections and low-latency local game streaming. Apps like Sunshine/Moonlight (local game streaming), Hamachi, and Radmin VPN (LAN emulators) cannot function properly. The client devices can technically "handshake" and connect to the host PC, but immediately after connecting, the video stream freezes completely, or the connection experiences ridiculously high latency / packet loss, making it completely unusable. Here is everything I have already tried to troubleshoot, which did not resolve the issue: Network Properties:…

I mean, the instant reset Call In or Chat is out of order. Tried that many many times and no phone number or instant Chat came up. Only more of the same questionnaires over and over again and a FAQ suggestion. Users shouldn't have to wait a whole day hoping to get an email reset to use their computers when an activation needs to be reset because the other options are just so difficult to use if they haven't been discontinued. Users should be able to log into their accounts and reset their activation like so many other software companies allow. But in virus protection it's far more important to have an instant reset somewhere because sometimes we feel our whole computer is…

Hi, here is the info required from the read first list: Step 1: Operating system and version info. O/S Version: Win 11 Pro v25H2 (OS Build 26200.8246) Step 2: App name and version info.

Event viewer states "Updated Kaspersky Internet Security status successfully to SECURITY_PRODUCT_STATE_SNOOZED." from source SecurityCentre twice…

I'm in Windows 11 Home, Kaspersky Internet Security, application version: 21.3.10.391 (m) For almost a week now, Discord app was stuck on eternal 'update failed, retrying' loop whenever you tried to start it up. I tried all possible fixes available only to realize it's not an issue with Discord itself but with Kaspersky. When I turn it off, Discord updates normally and is back up and running but then breaks again after some time and loading screen spinning indefinitely when Kaspersky is enabled again. It must've been one of the recent updates that fried it. Any ideas how to fix it? Would adding it to exemptions work? Discord seems to be installed directly in app…

Hi, is there a way to set avp.exe high priority in Windows Task Manager in order to give Kaspersky Internet Security full resources while running a complete scan of a 2TB drive (without the need to make exceptions) at least once?

Hi Guys, I use burpsuite to intercept my packets, when ever I turn on my burpsuite’s proxy and try to intercept the packets I get an error message from my kaspersky antivirus (image attached below). If I turn off my burpsuite’s proxy to default system proxy setting I’m able to browse the internet. Is there any solution other than disabling my antivirus while I’m intercepting? If there is any please do share it with me. Thanks in advance! Cheers :)
