What are Sumatranbox pop-ups?

Sumatranbox popups are a consequence of adware action. Adware is a kind of malware that shows you the pay-per-view of pay-per-click promotions, which produces a massive amount of earnings for adware representatives. These promotions may have explicit material, or have a link to malevolent content/website, considering that adware maintainers have no reason to examine the goodness of the material they are going to show – their solitary target is cash.

Pop-up marketing itself is a good, affordable and also really efficient advertising tool¹. It enables the vendor to attach the customers’ attention to their site, as well as the buyers to receive the dynamic updates on the goods they intend to purchase. When the person will get a pop-up alert that the TV set he desires to purchase is available at the online store he/she visited previously with a 15% discount, one will definitely use this possibility and get it. Considering the exceptionally low price for the popups and their targeting, such an advertising instrument is a much-loved thing amidst the advertising teams of huge online sellers.

However, such a profitable scheme could not be missed by virus developers. Potential to demonstrate the popup advertisements forcibly to the targets of malware invasion is an ideal basis for malevolent manipulations with the popup ads. And Sumatranbox.com ads is among hundreds that are “employed” in this scheme.

How have I got the Sumatranbox virus?

There are a lot of ways of getting infected by the adware that lead to the Sumatranbox popups tornado. A lion’s part of this virus incidents is after the freeware or cracked programs, that are spread on the peering networks. Free software may likewise be downloaded from the official site, and the adware is offered as a legitimate bundled program.

There is no need to blame yourself. A number of users frequently use the dubious programs from untrusted providers: abandonware, different utilities that are free, and even hacked programs. All of these kinds of applications are dangerous, since it is quite easy to build in a Sumatranbox malware under the cover of part of the license hacking script, or as a component of the self-made algoritm inside of the Windows optimization tool.

Sumatranbox popup virus can also be hidden in the advertisement somewhere on the unusual website. Such websites are usually packed with intense and blinking advertisements, and their proprietors often approve any promos to be posted on their page. Thus, clicking on such banners is a risky thing: only the advertisement contractor realizes what will happen when you click this advertisement. Besides some “light” viruses, like adware or undesirable programs, you can also receive something much more risky, like ransomware or coin miner; the big share of coin miners circulation is exactly after the malicious advertisements.

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

Potentially undesirable applications, like Sumatranbox popup virus can provoke a lot of different problems on your personal computer. Distracting is not the single problem – pop-ups can display you the promotions, where you are offered to get one more unknown application, or “a effective anti-malware tool”. Scareware is usually spread with the last motto. Potentially undesirable applications, in turn, may have spyware functions. And it is quite 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 ads are also used as a distribution way by various trojan viruses, for example – coin miners. The consequences of actions of such malware is 100% unwanted, and can cost you several hundreds of dollars. And even if you are not clicking these advertisements, they may be clicked by someone who also uses your 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 and money loss. It is recommended to wipe out the viruses with antivirus applications as soon as possible.
