Lib1.biz popups are an effect of adware activity. Adware is a type of malware that shows you the pay-per-view of pay-per-click advertisements, which produces a large volume of profit for adware representatives.

Pop-up advertising itself is an excellent, affordable and really productive advertising method¹. It makes it possible for the seller to link the buyers’ attention to their site, and the customers to receive the dynamic updates on the goods they intend to purchase. When the customer will receive a pop-up notification that the TV set he wishes to buy is offered at the online store he/she visited previously with a 15% price cut, one will surely use this opportunity and purchase it. Taking into consideration the exceptionally small cost for the popups and their targeting, such a marketing instrument is a favorite thing among the marketing departments of big internet stores.
