Sdwsduniv popups are an outcome of adware action. 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.

Therefore, clicking such banners is a shot in the dark: only the advertisement provider realizes what will occur when you click this ad. 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.

Potentially undesirable programs, like Sdwsduniv popup virus can initiate a wide range of troubles on your PC. Distracting is not the single problem – pop-up notifications may present you the promotions, where you are offered to get another strange application, or “a effective security tool”. Scareware is often distributed with the last slogun. Potentially undesirable applications, in turn, can have spyware functions. And it is quite hard to distinguish the undesirable app from a normal one, if you don’t know the exact names. Besides the PUPs and dubious antiviruses, popup-related ads are also chosen as a distribution way by different trojan viruses, for instance – coin miners. The consequences of actions of such viruses is 100% unwanted, and can cost you hundreds or even thousands of dollars. And even if you are not clicking these ads, they can be clicked by whoever who also makes use of your personal computer – parents, children, spouse, etc. So the situation may become much more serious, and it will be much harder to solve it without data loss.
