all waste information none is working
some are indeed outdated. Was disappointed to see that K9 is obsolete
There is a pretty massive bug in the Kurupira program.
I’ll share my tale. Whilst doing a routine Google search into an Israeli charity, I was met with a load of porn sites in my search results. I did not know that my regular filters had been turned off, so I naturally assumed that there were ‘holes’ in my current program. I did a Google search and came to this webpage, and downloaded the Kurupira program on the recommendation of this page’s author. I soon found that Kurupira was blocking google.co.uk. As this is my homepage, I could not even access the internet without disabling Kurupira. I later discovered that my regular filters had been turned off, and, finding that the offending search results were no longer appearing on Google, I decided I ought to remove the over-zealous Kurupira program.
I found that in order to uninstall the program, it had to be disabled. I disabled it, but the uninstaller said that the program was still running. But there is no facility to disable the program any further than I already had! I went to the maker’s website, but there was no help to be found there. The ‘Forum’ link does nothing more than changing the language of the homepage, and there is no Help or Information facility there at all. There is not even a ‘Contact Us’ facility on the site. Because there is an advertised danger of mucking-up Windows if I shut down the program via Task Manager, I am currently having to get by putting the program into Sleep Mode every three hours – which is very annoying.
I may well in the future have to use the program’s Feedback facility to report every good website that is blocked – but I have no idea how long it would take the makers to get back to me, amend the filters, and allow me to surf freely. All in all a pretty rotten experience.
I hope you will amend this page to make subsequent visitors aware of the bug in this programme. TW
Sorry you seem to be having some trouble with Kurupira.
I installed it to have a look and it worked fine in Windows 7 but didn’t seem to block anything in Windows 10. It certainly didn’t block Google or any websites that would be considered OK.
When uninstalling, all I did was exit the program from the system tray and then proceed with the uninstall. After a reboot, there is still an entry in the install list. I selected that entry to uninstall and it was all gone.
I think the problems you are having might be more specific to you as opposed to widespread bugs or issues with the program.
I would like to add my displeasure with Kurupira as well. It does not work with Internet Edge. And when I tried to uninstall it, I am having the same problems as the above poster. I have emailed for help but not sure I will get any kind of response. So frustrating that it cannot be disabled. Even more frustrating that it just doesn’t work with all search engines. Especially the popular internet edge.
The program can be disabled by right clicking on its tray icon, then you can uninstall. Don’t choose sleep but exit from the tray. Like I said above, it uninstalled fine after that.
Failing that, it uninstalls without issue from Safe Mode
Kurupira doesn’t seem to do much at all in Windows 10 and I would say avoid it if you have anything newer than Windows 7 installed.
very good software. I am sure God Himself will be very much happy with this.
There is one missing: Bloxxx: Porn Blocker. The best for iPhone and iPad. Highly customizable.
I have a great one! It’s called Sophos. It is for malware filtering but has other awesome features, for instance, it can block websites with viruses. You can also warn you when you are visiting a questionable site or block it entirely. The only thing is that I’m not sure it works on Windows devices.
Block entirely
Thanks it is help me to some ecces things
You can also use stop-it.be
These tools are awesome. I am also using another filter which works perfectly. Visit pornguard.org for using this awesome tool
very good software! We should do hard work together to destroy this ugly pron-network. and that’s our duty to spread that types of software all our the world by some means like facebook,twitter,youtube etc>>. and i’m sure that one day we all will do this….first we change ourself then to other’s…………….
Actually it can save or break marriage. There should me a way to block pornography without giving anyone a warning page. that way a ” blaming” game can be avoided between couples…otherwise the trust issue comes on…yes we want to trust our spouses but its hard if they go behind our backs and do this…that comes to men and women
CC, your comment is illogical as written.
When porn or other inappropriate content is blocked, and a warning/block page or 404 page not found error is displayed, it is quickly apparent what is going on. Exactly how would this avoid a “blame game?” You say that blocking with a warning/block page results in “trust issues.” What do you think will happen if you try transparent/surreptitious monitoring of your spouse, without a frank/honest discussion? If you want to promote trust, try being frank/honest with your spouse about your concerns. If the relationship can’t endure frankness/honesty, it isn’t much of one.
Wonderful programme
On our last computer I kept telling this person to stop going to porn sites, viruses, etc. can infect computer. I do believe with all tools/apps/programs in place, some malware etc. got through due to porn surfing. Now, we have a new computer, same person is surfing porn again. I never researched porn filtering programs when we had last computer. Just started today/tonight.
Which program to go with? I would prefer one that did most of the work vs. me having to monitor and white or black list sites and a program that wouldn’t be to obvious to other users that a program is installed filtering.
Thanks!

Thank you so much for this, it may help save my marriage.
