How can I filter my internet connection based on content?

All we need is an easy explanation of the problem, so here it is.

I have a WinXP PC that my children (4-14 years old) use but want to restrict some internet activity to prevent them from being exposed to some of the questionable and adult content that is available.

We have to PC in the living room so we can monitor them as much as possible but when unattended I want a second check.

What are my options and is there free software that works?

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

You might want to consider using OpenDNS (, though it’s strictly not based on content but on domain names.

Method 2

Use Dansguardian, though I’m not sure how to set it up for a Windows PC

And we had questions like this before:

Here’s Joe answer from there (kudos to Joe):’s Top 5
Internet Safety Tips

  1. Tell your child to NEVER EVER reveal their name, address, phone
    number or any other personal
    information to ANYONE online. Once you
    give out this information, it is
    impossible to retract.

  2. Communicate regularly (not just once) with your child about WHAT they
    do online and WHO they talk to online.
    If you have actually met the friends
    they are talking to in person, you’ll
    know it is OK for them to chat with
    them online.

  3. Take computers out of children’ rooms and put them into public areas
    such as the family room. Many parents
    think they are helping with homework
    by giving the children a computer, but
    it also opens certain dangers that you
    may be unaware of.

  4. Choose your child’s screen name, email address or instant message name
    wisely – don’t’ reveal ages, sex,
    hobbies, and CERTAINLY NOT suggestive
    or sexy names. Predators are more
    likely to pursue a child with the
    screen name “sexyteen5” than

  5. Use technology to help you protect your child. Monitoring
    software gives you the ability to
    review your child’s Internet usage.
    Even if you don’t look at each and
    every email or instant message they
    send, you’ll have a good idea if they
    are making smart choices online.

Method 3

I generally recommend K9 Web Protection. It works, is fairly simple to administer and I’ve had no complaints from the users I’ve set up with it.

Method 4

Let me just add to the OpenDNS band wagon a little.

First a plug that I use it at home and work and love it.

If you are using a connection that includes a router, (especially wireless) it is well worth learning how to set the DNS servers at the router, that way all the laptops, ipods, wiis and such get the same filtering.

Also if you don’t have a static ip, take the time to research and install dynamic ip updating. For example our internet ip address changes each time the dsl wireless modem/ router restarts (power outage, etc.). When this happens since OpenDNS filters content to your ip address based on your personal preferences, it needs to know what the current address is. There is a very small easy to setup and use automatic updater to take care of this for you.

Method 5

Windows parental controls would be a start if you have seven or vista. You could always buy a net nanny or norton 360 v3 (norton has a good parental control if you use vista). Use Mozilla firefox and adblock plus. Firefox has parental add ons.

Method 6

You can checkout this link:
It talks about firefox plugins for content filtering(links to these plugins are also given) as well as Web filtering software’s.

Method 7

Glubble (a modification of the firefox browser) would probably be worth looking at. It works on a whitelist system, which makes it very restrictive, and would therefore be more useful for the younger children.

You could also instate a system of observation, install VNC on their computer, allowing you to watch what they are doing. You may find that just telling them you can see what they are doing is a more effective deterrent than any filter.

Method 8

Norton Online Family provides control of content based on categories which can be set up by Windows login. Using different logins enables Younger children to view content appropriate for their age but allows teenagers more freedom. IM can be restricted to approved contacts and time restrictions can be set-up to prevent late night surfing.

Method 9

What you’re looking for is a keyword filter. This is the best way to filter any content because it can catch almost 100% of what you target. Eg. if you’re addicted to the game Warcraft, you simply add that to the keyword, and that will be gone from the internet.

The best solution here is on Firefox version 56.0, using Procon latte filter. This extension no longer works on the later versions, and it’s no longer on the addon store.

Good Basic Introduction to features on Windows

What sets it apart from other keyword based filters, is the accuracy, and minimal false positives. Plus its totally free and has password protection on addons page.

Some keyword blockers are overly aggressive. eg. if you set it to block the word, “bra”, it will block “branding”, “brain”, “library” as well. This makes it pretty much unusable.

Instructions on how to set this up on Firefox Windows and Android

Firefox 56.0.2 download,

Procon latte filter has been removed from Firefox addon webpage. You can download it directly from github.

Note: above will work on android too. Just open the install.html. This is workaround, details in stack overflow post.

Note: Use and implement method 1 because this method fully tested our system.
