Op00.biz popups are a result of adware activity. Adware is a type of malware that presents you the pay-per-view of pay-per-click promotions, which produces a significant volume of earnings for adware suppliers.

Pop-up advertising itself is a very good, cheap and also extremely efficient advertising instrument¹. It makes it possible for the vendor to link the customers’ attention to their website, and the buyers to receive the dynamic updates on the goods they want 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 checked out earlier with a 15% discount, one will surely use this possibility and purchase it. Considering the very small cost for the popups and their targeting, such a promotion and marketing method is a much-loved thing among the advertising departments of large online sellers.

However, such a profitable system could not be missed by virus creators. Ability to show the popup ads forcibly to the targets of malware attack is a perfect basis for malevolent tricks with the popup advertisements. And Op00.biz advertisements is among hundreds that are “employed” in this scheme.

Op00.biz popup malware can additionally be hidden in the promotion somewhere on the unusual web page. Such websites are generally full of bright and blinking advertisements, and their owners usually accept any type of promos to be placed on their page. For this reason, clicking such banners is a risky thing: only the advertisement contractor knows what will occur when you click this ad. Besides some “light” viruses, like adware or undesirable programs, you may additionally receive something a lot more damaging, like ransomware or coin miner; the big share of coin miners distribution is exactly after the malicious advertisements.

Potentially unwanted applications, like Op00.biz popup virus may initiate a variety of different troubles on your personal computer. Distracting is not the single problem – pop-ups may present you the promotions, where you are offered to download one more strange program, or “a perfect anti-malware tool”. Scareware is often spread with the last motto. Potentially undesirable applications, in turn, can have spyware functionality. And it is pretty hard to distinguish the unwanted app from a good one, if you don’t know the exact names. Besides the potentially unwanted programs and dubious antiviruses, popup-related advertisements are also chosen as a distribution way by various trojan viruses, for instance – coin miners. The consequences of actions of such viruses is 100% unwanted, and can cost you several hundreds of dollars. And even if you are not interacting with these promotions, they may 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. It is recommended to remove the viruses with anti-malware applications as soon as possible.
