Adware is a kind of malware that shows you the pay-per-view of pay-per-click advertisements, which generates a large volume of revenue for adware distributors.

Pop-up promotions itself is an excellent, cheap and also extremely successful marketing method¹. It permits the seller to attach the customers’ interest to their site, as well as the buyers to receive the dynamic updates on the goods they wish to buy. When the consumer will receive a pop-up alert that the TV set he wishes to purchase is available at the online store he/she saw earlier with a 15% price cut, one will definitely use this opportunity and purchase it. Taking into consideration the incredibly low cost for the popups and their targeting, such a promotion and marketing tool is a favourite thing amongst the advertising teams of big online retailers.

Nevertheless, such a profitable scheme could not be missed by malware developers. Option to show the popup ads by force to the targets of malware invasion is an excellent basis for malevolent adjustments with the popup promotions. And Flunk.site promotions is just one of hundreds that are “employed” in this scheme.

Here is a summary for the Flunk.site

How have I got the Flunk.site virus?

There are a plenty of methods of becoming contaminated by the adware that cause the Flunk.site popups tornado. A lion’s part of this virus instances is after the free software or cracked programs, that are spread on the peering networks. Freeware can also be downloaded from the official web page, and the adware is supplied as a legitimate bundled program.

There is no need to blame yourself. A number of individuals frequently use the uncertain programs from untrusted providers: abandonware, various apps that are free of cost, and even hacked programs. Every one of these sorts of programs are risky, because it is very easy to include a Flunk.site malware under the guise of part of the license hacking script, or as a component of the self-made algoritm inside of the Windows optimization tool.

Flunk.site popup malware may also be concealed in the ad somewhere on the unusual website. Such web pages are usually filled with bright and blinking advertisements, and their proprietors typically accept any kind of promos to be published on their page. Thus, clicking on such banners is a risky thing: only the advertisement contractor knows what will happen when you click this ad. Besides some “light” viruses, like adware or unwanted programs, you may also get something much more unsafe, like ransomware or coin miner; the large 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 unwanted programs, like Flunk.site popup virus can provoke a lot of different troubles on your PC. Distracting is not the single problem – pop-up notifications may show you the banners, where you are offered to get another dubious application, or “a effective security tool”. Scareware is often spread with the last motto. Potentially undesirable programs, in turn, may have spyware functionality. And it is pretty hard to distinguish the undesirable app from a legit one, if you don’t know the exact names. Besides the PUPs and pseudo antiviruses, popup-related promotions are also exploited as a distribution method by different trojan viruses, for instance – coin miners. The consequences of actions of such malware is 100% unpleasant, and can cost you hundreds or even thousands of dollars. And even if you are not interacting with these promotions, they can 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 solve it without data loss. It is recommended to wipe out the viruses with anti-malware programs as soon as possible.
