Shelblock is a freemium software. So it is possible to use it for free, but also by paying for a version with more features.
The free version allows you to block ads on all your browsers. It offers the ability to have secure browsing that includes privacy protection and tracker blocking.
The paid version blocks all ads on your computer. It stops ads on streaming services like Youtube or Twitch and also on music services like spotify and deezer. In the same way, ads on social networks (Facebook, Twitter, Pinterest and linkedin) are blocked.
Secure browsing is significantly enhanced for the premium version with threats and scams, malware and cryptojacking sites blocked.
Finally, the Parental Control feature allows you to secure your children's online environment. For example, Shelblock Parental Control will filter out inappropriate search results, block malicious sites such as pornographic sites, gambling sites or even those selling weapons.
As a parent, you can access the settings to customize the control. You will also be able to add sites to block.
