A “filter” is a software package that can prevent access to cyber sites with illegal or damaging contents.
Efficiency depends on the software΄s inventiveness and on the degree to which lists with forbidden internet locations are updated.
Different filters are efficient preventing access to websites of different contents. For instance, a filter can prevent access to pornographic sites more efficiently, whereas another one can better prevent access to violent or racist sites.
Some of the internet service providers have already installed filter software programmes in the services they offer. In this case, you do not have to install other filters.
You can purchase software filters at the official points of software sale in our country.
