What are Rainbowblocker pop-ups?

Rainbowblocker popups are an effect of adware action. Adware is a type of malware that presents you the pay-per-view of pay-per-click ads, which produces a massive amount of income for adware distributors. These promotions may contain sometimes shocking information, or have a web link to harmful content/website, since adware maintainers have no reason to examine the goodness of the material they are going to reveal – their solitary target is money.

Pop-up marketing itself is a good, affordable and extremely efficient marketing method¹. It makes it possible for the seller to link the customers’ interest to their site, and the customers to get the dynamic updates on the goods they wish to purchase. When the person will receive a pop-up alert that the TV set he likes to buy is provided at the online shop he/she checked out previously with a 15% price cut, one will undoubtedly use this chance and purchase it. Considering the exceptionally low price for the popups and their targeting, such an advertising method is a favorite thing amidst the advertising teams of huge online stores.

However, such a successful plan could not be missed by virus creators. Ability to demonstrate the popup advertisements forcibly to the victims of malware invasion is a great basis for evil-minded tricks with the popup ads. And Rainbowblocker.com ads is just one of hundreds that are “employed” in this system.

Here is a short info for the Rainbowblocker site

How have I got the Rainbowblocker virus?

There are a lot of methods of getting infected by the adware that create the Rainbowblocker popups storm. A lion’s part of this virus instances is after the freeware or cracked programs, that are spread on the peering networks. Free software may also be downloaded from the official web page, and the adware is delivered as a legitimate bundled program.

There is no need to blame yourself. A huge amount of individuals frequently make use of the uncertain programs from untrusted sources: abandonware, different utilities that are free, or even hacked programs. All of these kinds of software are dangerous, because it is very simple to include a Rainbowblocker malware under the cover of part of the license hacking script, or as a component of the self-made algoritm within the Windows optimization tool.

Rainbowblocker popup virus can also be hidden in the advertisement somewhere on the odd website. Such sites are usually packed with intense and blinking advertisements, and their owners typically accept any kind of promos to be placed on their web page. Thus, clicking such banners is a shot in the dark: only the advertisement provider realizes what will happen when you click this ad. Besides some “light” viruses, like adware or undesirable programs, you can also receive something much more damaging, like ransomware or coin miner; the large share of coin miners distribution is exactly after the malicious advertisements.

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

Potentially unwanted applications, like Rainbowblocker popup virus may initiate a lot of problems on your PC. Distracting is not the single problem – pop-up notifications may show you the advertisements, where you are offered to download another unknown application, or “a perfect anti-malware tool”. Scareware is often distributed with the use of the last slogun. Potentially undesirable programs, in turn, may have spyware functions. And it is quite hard to distinguish the unwanted app from a legit one, if you don’t know the exact names. Besides the PUPs and pseudo antiviruses, popup-related ads are also used as a spreading way by different trojan viruses, for instance – coin miners. The consequences of activity of such viruses is 100% unpleasant, and can cost you hundreds of dollars. And even if you are not clicking these banners, they may be clicked by someone who also makes use of your computer – parents, children, spouse, etc. So the things may 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 antivirus programs as soon as possible.

Nevertheless, due to its large resources utilization, as well as some bugs that may be serious for some groups of users, Defender is often disabled by the users, so its use is likely impossible.
