Tested with K9 Web Protection version 4.4.268 on Windows Vista SP2 (32-bit). and31415 has posted an answer which requires no extra (paid) software. If anyone has a method that is simpler or doesn't require the use of paid software, feel free to post it, and I'll try it out and select it as the answer if it works. I wish I could give an answer using free software, but this is the only solution that worked so far. I tried deleting C:\Windows\System32\drivers\bckd.sys and restarting the computer.Įdit 2: I figured it out and the answer is below, with one caveat: it requires paid software (albeit a free trial of paid software if you have never used it before).
I tried installing my own license file like it says in this link (K9 doesn't allow you to download license files anymore).I tried reinstalling K9 and then trying to uninstall.I tried the usual uninstall method from control panel.Is there any way to uninstall this program without the password and email information?Įdit: I forgot to mention that I tried several methods to uninstall, and so far none have worked:
#K9 web protection sign in install#
I also can install Cygwin or boot to a live USB if that would help. I do however have administrative access to the computer. I'm trying to uninstall K9 from a Windows Vista 32-bit computer, and I do not have the K9 admin password or know the K9 admin email.
