Adware is a type of malware that presents you the pay-per-view of pay-per-click promotions, which generates a large volume of earnings for adware distributors.

Pop-up promotions itself is a good, low-cost and also extremely efficient advertising method1. It makes it possible for the vendor to attach the buyers’ interest to their website, and the customers to get the dynamic updates on the goods they want to buy. When the customer will receive a pop-up notification that the TV set he wishes to purchase is offered at the online store he/she visited earlier with a 15% price cut, one will surely use this chance and buy it. Considering the extremely low price for the popups and their targeting, such a marketing tool is a favorite thing amidst the marketing departments of large online retail stores.

However, such a rewarding strategy could not be missed by virus developers. Ability to show the popup advertisements forcibly to the targets of malware attack is a perfect basis for malicious adjustments with the popup ads. And Sdwsduniv.biz advertisements is among hundreds that are “employed” in this system.

Besides some “light” viruses, like adware or undesirable programs, you can also receive something far more threatening, like ransomware or coin miner; the big share of coin miners distribution is exactly after the malicious advertisements.
