I am loss for el67.sjstny.com and el96.sjstny.com pop-ups
El67.sjstny.com and el96.sjstny.com are questionable websites that look like have nothing with other malicious sites. But they can be installed to random computers bundled with free software that is available on the Internet. Although it is possible to refuse installing those programs during the installation of the main software, quite often users skip many steps of the installation just to make it quicker and this way they end up getting additional unwanted programs.
