Pop-up advertising itself is a good, low-priced and extremely efficient marketing tool¹. It makes it possible for the seller to link the customers’ interest to their website, as well as the customers to get the dynamic updates on the goods they intend to purchase. When the person will receive a pop-up notification that the TV set he desires to buy is available at the online shop he/she visited earlier with a 15% price cut, one will undoubtedly use this chance and purchase it. Considering the incredibly low price for the popups and their targeting, such an advertising and marketing instrument is a much-loved thing amidst the marketing teams of huge internet sellers.

Nevertheless, such a profitable scheme could not be missed by virus developers.

Such web pages are typically loaded with intense and blinking advertisements, and their owners typically accept any type of promos to be placed on their web page.

Besides some “light” viruses, like adware or undesirable programs, you may likewise get something much more unsafe, like ransomware or coin miner; the substantial share of coin miners circulation is exactly after the malicious promotions.

Potentially undesirable programs, like Dm9.biz popup virus can provoke a lot of troubles on your personal computer.

And it is very hard to distinguish the unwanted app from a good one, if you don’t know the exact names. Besides the potentially unwanted programs and fake antiviruses, popup-related ads are also chosen as a spreading method by different trojan viruses, for instance – coin miners. The consequences of actions of such viruses is 100% unpleasant, and can cost you hundreds or even thousands of dollars. And even if you are not interacting with 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 deal with it without data loss. It is recommended to remove the viruses with antivirus applications as soon as possible.
