How can the display of pornographic pages on a computer be permanently prevented, given a lack of experience with computers?

Browsing pornographic websites, looking at nude images, and watching explicit sexual films are haram (forbidden).

If you have fallen into any of these, repent sincerely to Allah, resolve never to return to them, and regret what you have done. If you fall again, seek your Lord's forgiveness and do not despair.

A Muslim observes Allah and fears His punishment, and this is a self-deterrent from sins.

You do not only need a program to prevent you from what is forbidden, but also to strengthen your faith and awaken your conscience, and to be aware of the schemes of the enemies of Islam.

We advise you to occupy yourself with what benefits you in this world and the Hereafter, and to keep good company.
