    I can't type anything after installing prevx free version 3.0.5.104 today; the keyboard is not working at all. i suspect it is the new module pxkbf.sys, prevx keyboard security, that caused this. I have removed my keyboard device driver and update the latest driver from microsoft. I have changed new battery to eliminate that possibility. The device driver shows that the keyboard is working properly and has good battery level and strong wireless signal. My mouse and keyboard is from the same microsoft wireless desktop set, and the mouse has no problem operating. I have removed prevx 3.0.5.104 and update to the latest version 3.0.5.106; uninstall both versions; and even using official prevx remover; still couldn't get my keyboard back again. Either prevx messd up with keyboard device driver and/or incompatible with KAV as i notice that the pdm askes for approval of driver/pxkbf.sys intercepting keyboard stroke which i did allow, but the strange thing is that the pdm pop up occur only right after uninstalling prevx, but not during or after prevx install or while its real time protection is running. Prevx is the only software i installed recently.

    If no one can resolve this issue, i am afraid i have to reinstall windows which is time consuming and i hate that. i probably would not touch in the cloud av again, especially prevx.

    Sorry for posting this; I should have done more research before posting the problem. I found the solution from microsoft support website, but I don't know if Prevx is really causing this; may be not. Method 1: Resynchronize your device with the receiver does solve my problem. This may be informative for those who may encounter the same problem.

    I had the same problem.

    Yesterday, I installed the new version of prevx 3.0.5.106. After that, prevx would to reboot the pc to enable the monitor. I rebooted but my mouse and my keyboard (with PS/2 interfaces) stopped to work. I tried to visit this link http://support.microsoft.com/kb/838398, but nothing. Then I tried to disinstall prevx. Nothing again.

    I reformatted my pc and now all it is ok. Any solutions before installing prevx again?
    Thanks for your attention. Best regards.

    if you removed prevx and keyboard still was not working prevx is most likely not to blame. do you have the latest patches and drivers for your machine and various software on it? If yes try prevx again

    Hello all,
    Please let me know if any problems persist with keyboard protection. It looks as if tcyca solved their problems but it could be down to an AV blocking Prevx from installing properly or other hardware layer incompatibilities.

    Ensure that if you do uninstall Prevx, do not remove files manually - remove them using the build-in uninstaller, as Windows requires a specific sequence of routines to remove entries within the system.

    Thank you for the help! :)

    I had a problem with 106 too. I could boot to the Windows login screen but my mouse and keyboard wouldn't work, so I couldn't login (even in safe mode :mad: ). This only occured when I rebooted after uninstalling keyscrambler (which I just found too annoying to live with), so it could be unrelated to prevx.

    I have everything back to normal now (thankfully I keep regular images of windows installation on C: and my user documents are on another drive :D ), and I have now re-installed prevx from the website (version 3.0.5.106).

    I would be interested to see a changelog for 106.

    Hi Joe, I will try to reinstall prevx tomorrow..Yesterday I encountered this behaviour. In any case, if the problem will persist, How can I fix this problem?
    Is Prevx 3.0.5.106 an official release or not? From this forum I see that Prevx 3.0.5.106 is marked as RC. What does RC stand for? I think release candidate but I'm not sure.

    Thank you for your attention.

    I want to know if its RC (Release Candidate) as well. I got version 106 from a clean install of the "latest" version so I guess its an official release but we've not had an official view posted yet.

    Hi pling_man,

    I see that you have reinstalled prevx (3.0.5.106). Does it work for you? or do you encounter the same problem (mouse and keyboard stop to work)? I won't to reinstall prevx if the problem persist. :'(

    Edit: to be clear, I will reinstall prevx when I'm sure that the problem will be fixed (I paid my full license, so I would have prevx installed because I find prevx a very good tool)

    Have a good weekend!!!

    Its working for me now. I just uninstalled everything using the windows uninstaller, then ran the prevx uninstall tool from the support website, then rebooted, then installed.

    Hello all,
    The uninstall issue with KeyScrambler does appear to be a bug in Prevx's protection, although under normal circumstances Prevx should not negatively affect the performance of your keyboard.

    Build 106 does not have any keyboard-related changes in it, but I'll be posting a changelog shortly to clarify the other changes.

    In the meantime, you should disable Prevx protection when uninstalling KeyScrambler or other similar programs.

    Let me know if you find any other issues!

    I don't use KeyScrambler so that is the reason it doesn't affect my Desktop with MS Wireless keyboard and mouse? Great :D

    Thanks for the information PrevxHelp. The uninstall of keyscrambler seemed to work, but I couldn't reboot afterwards. Anyway its gone now and I'm up an running again. Thanks for confirming 106 as an Official Release too.

    Is there a sequence of action to perform the correct installation? Now my pc is clean (I've re-formatted it).

    Thank you for your attention.

    The exact direct link to Prevx removal tool (Version 1,2, and 3.0)

    http://info.prevx.com/removaltool.asp

    I use that to remove any possible leftovers that is not done by Windows uninstaller and reboot and then resynchronize my wireless keyboard again.
    I would wait to see if there are any more bug reports about this issue before installing prevx again. I don't know if the keyboard security module is relatively new feature of Prevx, but there may be some fine tuning (compatibility) before it is working flawlessly. I feel really fortunate that I do not have to reinstall the window again.

    What security program is flagging it? Because there are different file sizes! Any added info would be appreciated! It could of been modified by malware o_O Or your security app is flagging a False Positive! And from VirusTotal none flagged my version of it 0/42!

    EDIT: Some extra info in pictures!
