Webdefencerequired popups are an effect of adware activity. Adware is a kind of malware that demonstrates to you the pay-per-view of pay-per-click ads, which generates a significant amount of income for adware distributors.

Pop-up marketing itself is an excellent, low-cost and extremely productive marketing instrument¹. It makes it possible for the seller to attach the buyers’ attention to their site, and the buyers to receive the dynamic updates on the goods they intend to buy. When the person will get a pop-up alert that the TV set he wishes to purchase is provided at the online shop he/she saw previously with a 15% price cut, one will definitely use this chance and get it. Considering the exceptionally low cost for the popups and their targeting, such an advertising and marketing instrument is a much-loved thing amidst the advertising teams of huge online stores.

And it is quite hard to distinguish the undesirable app from a good one, if you don’t know the exact names.
