The Purpose of Offers4u Popup
Some PC users might consider that Offers4u popup do offers some discounts or bargains while the majority sees another way. They don’t believe that Offers4u really gives real offers but to bombard PC users with products by relentless popping up various ads to ruin surfing experience. By constantly popping up on a single machine, Offers4u manages to intercept traffic without knowledge; by bombarding users with products, Offers4u is capable of promoting potential business. The more products being sold via its advertising platform, the more money it gets; the more traffic it intercepts, the more popular it becomes and thus the more cooperative ties can be achieved.
to publish products to as many PC users as possible, Offers4u adopts JS technique and backdoor program to record online whereabouts so as to allow its maker to access such information for the analysis of people’s searching preference and thus for the decision as to where to put its own codes to access more people and what to publish to certain PC user for business promotion. Such behavior is allowed by law and in this industry; however, combined with other flaws found from Offers4u, such behavior can be potentially dangerous.
