    I wanted to document an edge case I encountered in February 2025 that ultimately took many months to fully diagnose. I hope this helps Kaspersky support or anyone experiencing similar symptoms. Summary of the problem It started on a physical Windows 7 Professional x64 workstation. The workstation contains critical old software I still use. After performing, using a physical genuine Windows 7 DVD, an in-place repair installation (installing Windows 7 over an existing Windows 7 installation), Windows booted successfully, but the keyboard and mouse no longer functioned. No mouse and no keyboard actions were possible. I could not get past the screen that required entering the product key. I tried multiple physical (used and band new) USB keyboards and mice. They did not work. After exhausting all options I could think of, I concluded the PC hardware – 17 years old – has become faulty. Because I could not restore normal operation on the physical machine, I eventually converted the installation to a Hyper-V VHDX in an attempt to continue troubleshooting. The same keyboard and mouse problem remained in the virtual machine. Sequence of events The sequence was approximately: Existing Windows 7 Professional x64 installation with Kaspersky installed. Windows began reporting filesystem problems during integrity checks (chkdsk reported errors that could not be permanently resolved, among other problems). The system was also experiencing NVIDIA graphics driver issues. To repair both the Windows installation and the driver problems, I performed an in-place repair installation. After the repair, Windows booted, but the keyboard and mouse no longer functioned. After numerous unsuccessful attempts to repair the physical installation, I created a VHDX using Disk2VHD and migrated the system into Hyper-V. After resolving the some storage-controller boot issues in Hyper-V, the exact same problem was still present. This eventually led to examining the keyboard class driver stack in the offline registry. During investigation I loaded the offline SYSTEM hive and examined: HKLM\SYSTEM\CurrentControlSet\Control\Class\ {4D36E96B-E325-11CE-BFC1-08002BE10318} The UpperFilters value contained: kbdclass 0klmouflt.k4w-21-19 The same filter was also present in the fallback ControlSet. Probable root cause Windows repair installation left the Kaspersky keyboard filter registered in the keyboard device stack while something about the filter installation itself was no longer valid. Windows continued attempting to load the filter during keyboard initialization, resulting in the loss of keyboard and mouse. Solution A. Keyboard recovery — offline registry repair 1. Load the Windows SYSTEM hive Identify the Windows installation drive. In my case it was D:. reg load HKLM\TEMP D:\Windows\System32\Config\SYSTEM 2. Check the keyboard class driver's UpperFilters reg query "HKLM\TEMP\ControlSet001\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}" /v UpperFilters Value: kbdclass 0klmouflt.k4w-21-19 The second entry was the Kaspersky keyboard filter. 3. Remove the existing UpperFilters value reg delete "HKLM\TEMP\ControlSet001\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}" /v UpperFilters /f Check the fallback ControlSet and removed its UpperFilters value if it contained the Kaspersky filter: reg delete "HKLM\TEMP\ControlSet002\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}" /v UpperFilters /f 4. Recreate UpperFilters with only kbdclass For ControlSet001: reg add "HKLM\TEMP\ControlSet001\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}" /v UpperFilters /t REG_MULTI_SZ /d kbdclass /f For ControlSet002, if applicable: reg add "HKLM\TEMP\ControlSet002\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}" /v UpperFilters /t REG_MULTI_SZ /d kbdclass /f 5. Unload the SYSTEM hive reg unload HKLM\TEMP Reboot Windows. Result: The keyboard began working normally. B. Mouse recovery — offline registry repair Similar approach. reg load HKLM\TEMP D:\Windows\System32\Config\SYSTEM reg query "HKLM\TEMP\ControlSet001\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}" /v UpperFilters Value: mouclass 0klmouflt.k4w-21-19 reg delete "HKLM\TEMP\ControlSet001\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}" /v UpperFilters /f reg delete "HKLM\TEMP\ControlSet002\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}" /v UpperFilters /f For ControlSet001: reg add "HKLM\TEMP\ControlSet001\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}" /v UpperFilters /t REG_MULTI_SZ /d mouclass /f For ControlSet002, if applicable: reg add "HKLM\TEMP\ControlSet002\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}" /v UpperFilters /t REG_MULTI_SZ /d mouclass /f reg unload HKLM\TEMP Rreboot Windows. Result: The mouse function was restored. C. Physical-machine recovery I’d imagine the same approach would work on the physical machine. For now, I’m going to stick to the VM, and repurpose the PC for something else. If anyone from Kaspersky has seen this behavior after an in-place Windows repair installation, I would be interested in knowing whether this is a known issue with the keyboard filter driver or whether there is an official recovery procedure.

    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. App Name: Kaspersky Standard App Version: 21.25.7.504 Step 3: Description of issue. I've been using Kaspersky Internet Security for a while and have been having issues the last month or so, I created a post outlining the issue here (https://forum.kaspersky.com/topic/being-snoozed-with-inability-to-recover-until-entire-system-rebootrestart-58762/) regarding it this morning. The advice given of switching to the new app client seemed to have worked but now no scan will go past 1% (0 files). I narrowed it down to the scanning of system memory, if I disable that option they run and complete very quickly if however its enabled as it is by default they get stuck and I cannot cancel the scan, it sits endlessly at 1% 0 files thinking about itself, the only way to get out of it is to reboot/restart the system. I did find a post referencing a incompatible software checker tool but windows is blocking me from launching or using the tool, even as admin. I started this thread as I believe since the other was in relation to Kaspersky Internet Security but this issue has arisen with Kaspersky Standard I should keep it in the relevant category. Any advice on how to get it to scan memory successfully would be appreciated.

    Hi there, Since a few days, I'm not able to launch the secured navigation. I have the message "impossible to launch the secure navigation". I restart my computer a few times but the problem remains the same. Does anyone has the same issue or can help resolve this problem ? My computer is running under W11. Thanks for your feedback JD

    Hello everyone, I would like to report a reproducible issue with Kaspersky Password Manager (App Store version 10.3.1) on macOS 26.0.1 (Tahoe, build 25A362). The application freezes immediately upon launch, showing no UI response until forcibly terminated. Observed behaviour After launching, the process kpm_app becomes stuck waiting for a blocked XPC port: This indicates that the app is trying to connect to an unresponsive or missing XPC helper service (com.kaspersky.kpm.bl.resolver), which never responds — resulting in a total freeze. Technical background The App Store build registers an internal XPC service com.kaspersky.kpm.bl.resolver. In macOS 26 (Tahoe), Apple introduced persistent sandbox XPC restoration: even after an uninstall or container cleanup, launchd automatically recreates the service entry on reboot. When that restored service doesn’t respond, kpm_app waits indefinitely on an XPC handshake during initialisation. Workaround (confirmed functional) Quit the app completely: Remove the broken resolver service: Delete the sandbox containers: In Finder → Go → Go to Folder… → ~/Library/Containers/ Delete the folder com.kaspersky.kpm.bl.resolver manually, then empty the Trash. Relaunch Kaspersky Password Manager. The app now starts and synchronises correctly. (Optional: create an empty file /Library/LaunchDaemons/com.kaspersky.kpm.bl.resolver.plist with zero permissions to prevent macOS from resurrecting the broken helper on next boot.) Expected behaviour The application should initialise its XPC connection dynamically during launch instead of relying on a persistent launchd registration that can become invalid in new macOS sandbox environments. Environment Component Version macOS 26.0.1 (Tahoe, build 25A362) Hardware MacBook Pro 16,1 – Intel i9 Password Manager 10.3.1 (App Store build) Distribution Mac App Store Reproducible Always, especially after restart Summary This appears to be a compatibility issue between the App Store sandbox and macOS 26’s updated XPC system. Removing or resetting the com.kaspersky.kpm.bl.resolver endpoint resolves the problem entirely. Please forward this to the macOS development team for validation and patching in the next release.

    Hello everyone, I’d like to report a reproducible issue with Kaspersky VPN Secure Connection (App Store version 3.5.0, build 30500.79.14444486) on macOS 26.0.1 (Tahoe). The application freezes immediately upon launch and remains unresponsive until forcibly terminated. Observed behaviour After launching, the ksec_app process becomes stuck in a waiting state, as seen in macOS diagnostic reports: This means the app is attempting to connect to a non-existent or unresponsive XPC helper service (com.kaspersky.ksec.bl.resolver), resulting in a permanent hang. Technical background The App Store build registers an internal XPC service com.kaspersky.ksec.bl.resolver. On macOS 26 (Tahoe), Apple introduced persistent sandbox XPC restoration. Even if the related container or plist is deleted, launchd automatically restores the entry at next boot. Since the restored service no longer responds, the VPN UI (ksec_app) hangs on the XPC handshake stage and never completes initialisation. Workaround (confirmed functional) Quit the app completely: Remove the stuck resolver: Delete the sandbox containers: In Finder → Go → Go to Folder… → ~/Library/Containers/ Delete the folder com.kaspersky.ksec.bl.resolver manually, then empty the Trash. Relaunch the VPN. It starts and connects normally after that. (Optional: to prevent macOS from recreating the broken resolver after reboot, create an empty dummy file /Library/LaunchDaemons/com.kaspersky.ksec.bl.resolver.plist with no permissions.) Expected behaviour VPN should initialise its XPC connection dynamically on launch, without relying on persistent system registration that may be invalidated by macOS sandbox changes. Environment Component Version macOS 26.0.1 (Tahoe, build 25A362) Hardware MacBook Pro 16,1 – Intel i9 VPN 3.5.0 (App Store build) Distribution Mac App Store Reproducible Always, after restart Summary This appears to be a compatibility issue between the App Store build and macOS 26’s updated XPC sandbox behaviour. Manual cleanup and deregistration of com.kaspersky.ksec.bl.resolver restores normal functionality. Please forward this to the Mac development team for verification and patching. Best regards, M. Kurzdym, PhD (UK)

    Hello, Since two days ago I have seen that I can not start up the Battle.net application when Kaspersky is enabled. This has happened to other programs before, so I would usually add Battle.net to "Specify Trusted Applications" but this is where the second part of the issue happens. When I add the Battle.net launcher to the list, my Kaspersky would immediately crash. I have sent in a crash report when it happened, but I doubt that would help me with my immediate issue. I have run Windows update, Networking driver check and Kaspersky update but none have seemed to help. Could you please advise on what I can do to mitigate either part of this issue? Thank you.

    I am not able to use expedia with secure keyboard. I am not able to type in the destinations under flight section as the system forces me to use Kaspersky secured keyboard for some reason! and that keyboard just doesn't work! Has anyone else faced this problem? even after disabling it from kaspersky privacy settings and restarting the browser, I am still struggling with this problem. Any solutions?

    How hard is it to give us an option to disable that very annoying popup? Your users have been suffering for years and have been asking for a way to get rid of the secure keyboard input popup while still having the feature ENABLED and working in the background, but things are the same even with your latest editions (Kaspersky Plus). I think whoever thought it was a smart idea to remind the user about it every single time shouldn't have the power to manage and develop your software. Im a paying customer since 2006 and I had to turn off this feature and live without it whenever it came out (it's definitely been 5+ years). I just moved to a new computer and I've been configuring my settings and guess I will still need to disable it and live without that feature for many years to come...

    So I have a Logitech-macro on my left mousebutton that I use in games and it worked fine before I installed kaspersky. Now whenever I'm ingame the macro does not work anymore, I've created exceptions for Logitech-GHUB and the game (Tarkov), but still the macro won't work. :(

    My Windows version: WIndows10 22H2 (OS Build 19045.4651) Kaspersky PLUS 21.18.5.438 The problem: After the lastest Kaspersky PLUS's Application update, my On-screen Keyboard becomes bugged. You can see from the 2 screenshots, my mouse cursor was positioned at Number 0, but it counts as Number9. I have been using Kaspersky for many years, and I use On-screen Keyboard for many years, this bug never happened to me before.

    Hi, I'm not sure wether this is the right forum or the right english term for it, but I have a problem with that little window that opens whenever I try to enter something into a searchbar. As seen in the screenshot, it completely blocks a large part underneath the searchbar for no apparent reason. A lot of the time it blocks auto completion or other stuff for several seconds, making the work process slower. I think I don't have to be reminded that the secure keyboard input is active everytime I want to enter something. Is there a means to have that box toggled off?

    I installed Kaspersky Total Security today, with a one year subscription. However, after it did a scan and restarted the computer, my keyboard and mouse have stopped responding. I tried other keyboards and mice, both wired and wireless as well but it did not work. But they still work on the biOS screen of the pc. I could not find a recovery boot option. So I would like to have help with this.

    Hallo! Habe soeben erstmals Kaspersky auf meinem Rechner installiert, der Grund war, dass am rechten unteren Bildschirmrand ein kleines quadratisches Fenster aufging mit der Meldung "quick driver update" - ich halte das für einen Virus oder sonstigen Trojaner oder Müll. Nach der Installation und vollständiger Systemprüfung erscheint das Fenster immer noch. Es lässt sich mit dem Task Manager unter "task beenden" wegklicken. Weiss jemand, was das "quick driver update" ist? - ein Virus, Trojaner, sonstwas?

    Hello. I just installed Kaspersky internet security and right away my Lenovo yoga 7i keyboard stopped working. Tried several methods before finding the registry method. Problem is, I follow all the steps, I delete the "klkbdflt" entry from the registry leaving only "kbdclass". I hit ok. Then when I close the registry, it comes back as it was: both entries appear in the UpperFilters. What do I do now? Please help, I need this machine for work. When I change it: When I open it again:

    Dear KIS Community I don't know why KIS block Brave Browser every first time launch it. When start browsing, it is blocked. Second time of launch it I can browse. Moreover, If I exit my second times browser window then third times is not work too. Unless reopen it (4th). Error by the following action like this. Moreover, I can't find the solution of such this case over Google also. Please help. If the problem still exist, might not renew license. Really bored.

    I have tried several times to figure out how to set my Kaspersky Plus to launch upon startup. There are instructions out there on the internet, but in the "security" area, there are so many places...& cannot figure out which one to use. I always purchase Kaspersky products & have never had a problem with any, however this one is really confusing me. I think it important that the app launch upon startup, otherwise how would I know if I'm protected. Thanks in advance!!!

    I have Kaspersky Premium. "Previous application launch failed". Apparently after few minutes when Windows boots, Kaspersky crashes and opens up again and displays this error. And it does the same several times again during the day. It's really annoying. I have contacted customer support and gave them all the necessary files (dump and system info files), It's been 3 weeks and I haven't heard anything back. I went so far as to fresh install the latest Windows 11 (ISO on Microsoft's website), but nothing changes. I do not have any cracked software and everything I installed are genuine and properly bought. I thought the issue may be due to system stability, so I did a memory test overnight and did some burn-in benchmarks and there are no errors. No other program on my system acts weirdly. I have also tried "Kaspersky removal tool" and did another installation of Kaspersky, but the issue persists. I am very close to uninstalling this for good, and I don't want to, I really like Kaspersky. Please help!
