What is the ruling on money earned from working in the field of computer software, which involves designing permissible advertising materials, while the same publications include impermissible materials designed by other colleagues?

If the magazine was established to promote forbidden things, then it is not permissible to work for it. However, if it is for permissible matters and includes some forbidden things, then it is permissible to work for it, provided your work is not related to the forbidden.
