Top 7 porn blockers for Windows to block porn on computer

#1 Cisdem AppCrypt

Compatibility: Windows 11 and Windows 10

Best for: Quit porn addiction, offering password protection and other flexible options.

Cisdem AppCrypt is our best overall porn blocker for Windows. We ranked it first because it can block more than 500,000 known adult websites with one click. It works well for people doing NoFap and for parents who want to restrict adult content on a child’s PC. Since a password is required to change the settings, quit the app, or uninstall it, the protection is difficult to bypass.

Key features:

• Block more than 500,000 known adult websites with one click.
• Add specific adult websites and webpages to the block list.
• Block URLs containing specified keywords, such as “porn”, “xxx”, or “sexy”.
• Block all websites except those added to the allowlist.
• Support Chrome, Edge, Firefox, Opera, and other popular browsers.
• Lock apps that may contain adult or inappropriate content.
• Apply restrictions permanently or during scheduled periods.
• Require a password to access the settings, quit the app, or uninstall it.

How to set up AppCrypt

1. Download and install AppCrypt on a Windows computer.

Free Download Windows 10 or later

2. When you open it for the first time, set a password.

To prevent your own access to porn, it's recommended that you ask someone else, such as a family member, to set the password for you.

3. Click the AppCrypt icon on the taskbar. Alternatively, right-click this icon and then choose Open Main Window.

4. Enter the password to access the main window of this porn blocker.

5. Click the Web Block tab and install the extension on the browser(s) of your choice.

6. In the Web Block tab of this porn blocker app, do any of the following things.

• Click the Block porn sites dropdown menu at the bottom and choose Always block. This will automatically block all adult sites.
• Enter a specific porn site in the URL field and click Add.
• Enter a keyword that you think is common in the URLs of adult sites and click Add.
• Click the Import dropdown menu and choose TXT file to import your own list of inappropriate websites.

7. If some apps on the computer contain adult content, you can add them to the block list under the App Lock tab.

Note: Unlike some Windows porn blockers, AppCrypt works with both administrator accounts (typically used by adults) and standard accounts (often used by children). This makes it usable for preventing porn access on computers for people of all ages.

There are several ways to permanently or temporarily unblock an item on the block list, such as removing the item from the block list or quitting AppCrypt. But any of the ways requires the password. In addition, if one attempts to unblock a porn site by turning off or uninstalling the extension, AppCrypt won't allow the extension to be turned off or removed. This makes the blocking hard to bypass, ensuring the tool’s effectiveness.

 

#2 DNS Angle

Compatibility: Windows 11, 10, 8, 7, Vista, and XP

Best for: Block porn on children's PCs and ensure their online safety.

DNS Angel is a free DNS-switching tool designed to block inappropriate content like adult sites, malicious sites, and phishing sites. Instead of blocking websites itself, it changes the DNS settings on your Windows computer to a family-safe DNS service.

Its biggest advantage is simplicity. DNS Angel provides four secure DNS options for users to choose from. Simply select one, and it will replace your current DNS server with the chosen DNS. Once applied, a significantly large number of porn sites will be blocked.

However, the custom block lists are not allowed in it. If certain inappropriate websites are not on the predefined block lists, you can’t add them. In such a case, you will have to wait until the updated predefined block lists include these websites. Users with administrator access can also restore the original DNS settings or choose another DNS service, making it easier to bypass than the password-protected porn blocker I mentioned above.

How to set up DNS Angel

1. Download DNS Angel to your Windows PC (preferably on a standard account). Unzip it. No installation is needed.

2. Open the tool.

3. Choose a predefined block list from the 4 options:

• Cloudflare Family: Helps improve browsing speed and automatically blocks most adult content websites.
• OpenDNS Family: Effectively protect your family from adult websites, phishing, and malware.
• Yandex Family: Offers the strictest adult-content filtering, though it may occasionally block normal sites.
• CleanBrowsing: Designed for families, blocks adult sites and restrict inappropriate searches.

To block porn for your child, I recommended the second one - OpenDNS Family.

Porn content will be blocked on all browsers on this Windows computer.

If your children use an administrator account on your Windows computer or their own device, it’s recommended to create a standard account before setting up this porn blocker. If they have administrative privileges, they could easily disable the blocking.

 

#3 Qustodio

Compatibility: Windows 11 and 10

Best for: Filter porn content for children and manage their digital wellbeing.

Qustodio

is a comprehensive parental-control app rather than a dedicated porn blocker. Web filtering is one of its main features. Once installing this app on your child’s device and set it up, most inappropriate websites are blocked by default. You won’t need to spend much time manually adding specific adult sites to the block list. However, Qustodio takes longer to install and configure than the above 2 simple porn blockers. Before the setup, make sure that your child has a non-admin account (i.e. a standard account).

It offers 2 different plans for you to choose from. With the Basic plan, you can enable safe search, filter adult content, and blocking porn apps on your child’s PC. The price is $59.95 per year. The Complete plan costs $104.95 per year and includes more advanced features such as web activity alerts, blocked website alerts, and more.

How to set up Qustodio

1. Go to Qustodio's official website. Click Sign up to create a parental account. Log in to the account.

2. Click Add child.

3. Enter your child's details and create a user profile for him or her. Click Next.

4. On your child's account on a Windows PC, download and install Qustodio.

5. Open the Qustodio app. Choose the I already have a parental account option. Click Next.

6. Log in to your account. Click Next and then Finish.

After setting Qustodio up, most porn sites are blocked by default. If you want to explore the web filtering feature of this porn blocker, go to its official website. In your child's profile, click Choose Rules > Web filtering. In the Categories tab, you will find that the Pornography category is blocked by default. In the Websites tab, you can manually add specific inappropriate sites to the block list.

Without knowing the email address and password of the parental account, your child won’t be able to quit the Qustodio app or change your settings.

 

#4 Norton Family

Compatibility: Windows 11, 10, 8, and 7

Best for: Remotely control child's computer and block inappropriate content online.

Norton Family is a cloud-based parental controls software. It is designed to help parents protect and monitor children's online environment remotely. It prevent children from being exposed to inappropriate content, especially pornography, violence, drugs, etc. by offering real-time content filtering. In this way, children cannot access pornographic content even if they use incognito mode or find new porn websites.

Compared to Qustodio, it supports fewer operating systems. However, it offers one standout feature that many parents may find extremely useful - set parental controls on YouTube.com. This allows you to see which videos your children have watched, as well as filter inappropriate videos.

How to set up Norton Family

1. Go to Norton’s official site. Create an account for yourself (as a parent).

2. Install Norton Family app on your PC or mobile phone. Sign in to your account.

3. Create another account for your child. Install this porn blocker on his/her PC. Sign in with his/her account.

4. Go back to the main window of Norton Family in your device. Go to the Parental Controls section. Follow the prompts to add your child’s account to your family.

5. Select your child’s age. Then it will apply pre-defined house rules based on the child’s age.

You can also manually adjust these rules. Such as setting the time your child is allowed to use his/her device, adding inappropriate or distracting sites to the block list. It also allows you to view your child’s online activities, search history, device usage time, etc. on your device at any time.

 

#5 Cold Turkey Blocker

Compatibility: Windows 11, 10, 8 and 7

Best for: Set up one or multiple block lists for yourself and increase productivity.

Unlike the porn blockers for PC mentioned above, Cold Turkey is not suitable for blocking adult content for children as it can be uninstalled easily. But it’s ideal for users who want to control their own online behavior. You can use it as a porn blocker on your PC by easily adding porn and other bad websites to a custom block list. Although it has a predefined block list, the list only contains a few porn sites, which is far from sufficient. Therefore, you still need to customize the block list manually. Thanks to its keyword blocking feature, you can also block common porn-related keywords, which can make numerous porn sites inaccessible.

To prevent yourself from disabling the blocking rules, you can lock the settings using a random text.

How to set up Cold Turkey Blocker

1. Download and install Cold Turkey Blocker on your computer. Open the app.

2. Install an extension on your preferred web browsers.

3. On the left, choose the Blocks section.

4. Open the default block list (called Distractions) or create a new block list.

5. In the dialog that opens, click Import > Web categories > Porn. This will automatically add a few popular adult sites to the block list.

6. In the Import menu, choose All URLs containing and then add keywords.

7. Manually add other porn sites that you want to stop access to.

8. In the Blocks section, click the lock icon next to this block list.

9. Choose a lock type to protect the blocking and then set it up. The Password lock is recommended for porn blocking, while other lock types can also be helpful.

Thanks to the lock, when the blocking is active (which is permanent by default), you can’t turn off the blocking.

 

There are some porn blocker extensions available for different web browsers. You can find them directly in each browser’s web store. The benefits of using porn blocker extension are that it doesn’t require you to install any software on your computer, and many of them are free to use. The drawbacks are that they can be easily bypassed, and usually offer fewer features than dedicated porn blocker applications.

Below are 2 best porn blocker extensions I’ve tested.

 

#6 BlockerX

Compatibility: All Windows operating systems

Best for: Quickly block two million known adult websites on Chrome and and improve your browsing experience.

BlockerX is a Chrome extension designed to block pornographic websites and help users control their browsing habits. Its Adult Blocker can restrict access to more than two million known adult websites and enforce SafeSearch on major search engines. You can also add specific website or keyword to block.

However, if this extension is turned off or uninstalled, both the adult content and any user-specified content that was previously blocked will become accessible. Luckily, the Accountability feature helps prevent the extension from being disabled. However, despite the Uninstall Protection feature, one can still easily uninstall BlockerX and access any website, including adult sites.

BlockerX now also offers a separate Windows app with more powerful features, such as the ability to block unsupported browsers, sync with mobile apps, and uninstall protection.

How to set up BlockerX

1. Go to Chrome Web Store.

2. Search for BlockerX. Click the first result you see, which should be Porn/Adult Blocker, Block Sites - BlockerX.

• Block porn sites by specifying the domain name: Click Blocklist in the left column. Type in the URL of adult websites to the box then click Add website. You can also block a specific porn webpage.
• Block porn sites by specifying the keyword: Go to Keywords tab. Add words/phrases to the box then click Add keyword. To prevent unintended blocking of several pages, you’d better adding phrases instead of word.

8. This step is optional but recommended. Turn on and set up the Accountability feature and Uninstall Protection feature.

 

#7 Cisdem Web Blocker

Compatibility: All Windows operating systems

FAQs

How do I turn on SafeSearch on Windows?

SafeSearch is a search-engine setting rather than a Windows setting. You need to enable it separately in Google and Bing.

• Google SafeSearch

Google provides a built-in SafeSearch feature. Once turning on the safe mode, Google will automatically filter out pornographic and other explicit content from your search result.

1. Open Safe Search settings on your browser.

2. Select Filter or Blur from the 3 options.

Google Safe Search filter will not catch all adult content, and it only works on the search result. If users go to a porn website directly, the filter won’t block them.

• Bing SafeSearch

Bing also has a safe search feature that filter out adult text, images and videos from your search results. But this filter is also not 100% accurate.

1. Go to bing.com. Click the 3-line icon in the upper-right corner.

2. Select Settings > More.

3. Under SafeSearch, select Strict. Click Save.
