How can you disable k9 Web Security without having to know the password. I heard something about making a cd of some sort but I do not know how to do it and would like some help. Please help this is very important to me.

You could use a proxy, that should get by it, unless K9 is blocking the proxy you are trying to use. In which case, find another one!

There are literally tons.

I googled around a bit (something you should try btw, this was from the first page), and found that removing the file bckd.sys from C:\Windows\System32\Drivers should do the trick.

As proxies go you could basically create your own proxy server in your own house with something like a plug computer.(Pretty neat stuff btw)

The CD thing I guess is a *NIX Live CD.
Try this by instance.

IMHO it is way better to talk your way around this. Instead of them setting up a Filter why not just put the computer in a public place of the house?(Like the dinning room.) Either way feel free to keep asking. ;)

Just by taking a quick look at the official web site, it looks as if K9 is installed locally.

Try to delete it.

That's the problem people were having online when I looked into it, it didn't want to remove itself without a password.

You probably could just go and manually delete the files, but if so, then it makes it pretty obvious that someone tried to circumvent it.

The other issue is that he _most_ likely doesn't have admin rights under Windows.

Indeed, I didn't even think of that very obvious problem :/.

That being the case, a quick Live CD/USB would be good for removing bckd.sys , or, dealing with it via a proxy.

@imcrafty: another thing you may want to try is privilege escalation. If you manage to get SYSTEM rights just kill the process K9 is running under. For this you might want to try http://explo.it.

I've dealt with k9 internet security at work, and it blocks sites pretty well. Once in the settings you can block sites by category(media, pornography, hacking etc....) I tried for a short time to get around it but to no avail. I think it is only for windows so if you dual booted a linux distro you could get around it that way.

No way to get or guess the password with some craftyness and without getting caught? The main goal here is to get internet access without giving it away that you have the access. So tampering with the actual program itself would just alert whoever installed it when it stops working and starts receiving errors.

You could try installing a Virutal Machine on your windows OS and run a linux distro on it and see if you can gain internet access that way. Then just don't put the program or any shortcuts to it in an easy place to find such as your desktop.

You'd have to be careful with virtualization though, the default option, at least when I've used it, was to use your Hosts' internet and using a loop trick to tell your guest OS it is connected by ethernet. You'd have to change that setting first, otherwise you'd just end up being where you started from.
