here I'm sharing a great web filter which can block every add, rubbish pictures in the adds on different useful websites and also rubbish sites. The great thing is: its license key is free. You'll download the software and also fill the form in which you have to give your email address in which the company will send you the key on your email address. I'm myself using it and found it excellent specially I get rid of adds and I also stopped other people from opening unethical websites on my system. So don't wait and click on the link below to get the software.
