What are B-cdn.net pop-ups?

B-cdn.net popups are an effect of adware action. Adware is a kind of malware that shows you the pay-per-view of pay-per-click promotions, which generates a significant volume of earnings for adware distributors. These ads may include sometimes shocking content, or have a link to harmful content/website, due to the fact that adware maintainers have no purpose to examine the goodness of the web content they are going to show – their single target is money.

Pop-up promotions itself is an excellent, low-priced and extremely efficient advertising method¹. It makes it possible for the vendor to link the customers’ interest to their site, and the buyers to receive the dynamic updates on the goods they intend to buy. When the consumer will receive a pop-up alert that the TV set he wishes to purchase is offered at the online store he/she saw previously with a 15% price cut, one will undoubtedly use this possibility and get it. Taking into consideration the extremely small cost for the popups and their targeting, such an advertising and marketing method is a favourite thing among the marketing departments of huge internet stores.

However, such a profitable system could not be missed by virus developers. Option to demonstrate the popup advertisements forcibly to the victims of malware attack is an ideal basis for malevolent manipulations with the popup advertisements. And B-cdn.net advertisements is just one of hundreds that are “employed” in this scheme.

There are a lot of ways of getting infected by the adware that result in the B-cdn.net popups storm. A lion’s part of this virus incidents is after the free software or cracked programs, that are spread on the peering networks. Freeware can additionally be downloaded from the official website, and the adware is delivered as a legitimate bundled program.

There is no need to blame yourself. A lot of users oftentimes work with the dubious programs from untrusted sources: abandonware, various tools that are free, or even hacked programs. All of these types of software are risky, since it is quite simple to integrate a B-cdn.net 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.

B-cdn.net popup malware may additionally be concealed in the ad somewhere on the odd website. Such websites are usually packed with colorful and blinking ads, and their proprietors usually approve any type of promos to be published on their page. Hence, clicking such banners is a risky thing: only the advertisement provider knows what will occur when you click this advertisement. Besides some “light” viruses, like adware or undesirable programs, you can additionally get something a lot more unsafe, like ransomware or coin miner; the big share of coin miners distribution is exactly after the malicious advertisements.

Potentially undesirable programs, like B-cdn.net pop-up virus can provoke a lot of problems on your PC. Distracting is not the single effect – pop-ups can show you the banners, where you are offered to get one more unknown application, or “a effective security tool”. Scareware is usually distributed with the last slogun. Potentially unwanted applications, in turn, may have spyware functions. 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 pseudo antiviruses, popup-related banners are also chosen 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 tapping these promotions, they may be clicked by whoever who also makes use of your PC – parents, children, spouse, etc. So the situation may become much more serious, and it will be much harder to deal with it without data loss. It is recommended to get rid of the viruses with antivirus programs as soon as possible.
