What are Ouo pop-ups?

Ouo popups are a result of adware activity. Adware is a kind of malware that suggests you the pay-per-view of pay-per-click ads, which produces a substantial amount of profit for adware suppliers. These promotions might contain explicit information, or have a link to malevolent content/website, considering that adware maintainers have no reason to examine the goodness of the content they are going to show – their single target is cash.

Ouo push notification.

Pop-up advertising itself is a good, affordable and also very effective advertising tool¹. It enables the seller to link the customers’ interest to their website, and the customers to receive the dynamic updates on the goods they wish to purchase. When the customer will get a pop-up notification that the TV set he desires to purchase is available at the online store he/she visited earlier with a 15% discount, one will surely use this chance and get it. Taking into consideration the extremely low cost for the popups and their targeting, such a promotion and marketing tool is a favorite thing among the advertising departments of big online stores.

Nevertheless, such a profitable plan could not be missed by virus developers. Potential to demonstrate the popup advertisements forcibly to the victims of malware invasion is an excellent basis for malicious manipulations with the popup ads. And Ouo.io ads is one of hundreds that are “employed” in this scheme.

Here is a short summary for the Ouo site

How have I got the Ouo virus?

There are a huge amount of ways of getting infected by the adware that create the Ouo popups tornado. A lion’s part of this malware cases is after the free software or cracked programs, that are distributed on the peering networks. Freeware can likewise be downloaded from the main site, and the adware is presented as a legit bundled program.

There is no need to blame yourself. A number of people regularly utilize the dubious programs from untrusted providers: abandonware, different apps that are free, and even hacked programs. Every one of these kinds of programs are dangerous, due to the fact that it is quite easy to build in a Ouo malware under the guise of part of the license hacking script, or as a part of the self-made algoritm within the Windows optimization tool.

Ouo popup malware may also be hidden in the ad somewhere on the strange web page. Such sites are typically full of bright and blinking advertisements, and their proprietors generally permit any kind of promotions to be posted on their page. Therefore, clicking on such banners is a risky thing: only the ad contractor realizes what will happen when you click this ad. Besides some “light” viruses, like adware or unwanted programs, you can additionally get something a lot more threatening, like ransomware or coin miner; the substantial share of coin miners circulation is exactly after the malicious promotions.

The statistic shows that people dislike popup advertising more than other types of promotions

Potentially undesirable applications, like Ouo pop-up virus can initiate a wide range of different troubles on your personal computer. Distracting is not the only effect – pop-up notifications can display you the banners, where you are offered to get another unknown application, or “a effective security tool”. Scareware is often distributed with the last motto. Potentially undesirable applications, in turn, may have spyware functionality. And it is quite hard to distinguish the undesirable app from a normal one, if you don’t know the exact names. Besides the potentially unwanted programs and dubious antiviruses, popup-related ads are also used as a distribution way by various trojan viruses, for instance – coin miners. The consequences of activity of such malware is 100% unpleasant, and can cost you several hundreds of dollars. And even if you are not tapping these ads, they may be clicked by whoever who also uses your PC – parents, children, spouse, etc. So the situation can become much more serious, and it will be much harder to deal with it without information loss. It is recommended to remove the viruses with anti-malware applications as soon as possible.

Nevertheless, as a result of its substantial resources utilization, as well as some failures that can be crucial for some groups of individuals, Defender is often disabled by the users, so its usage is probably impossible.
