What are Pu2.biz pop-ups?

Pu2.biz popups are a consequence of adware action. Adware is a kind of malware that suggests you the pay-per-view of pay-per-click advertisements, which creates a large volume of revenue for adware distributors. These promotions might have explicit material, or have a web link to malicious content/website, since adware maintainers have no purpose to examine the goodness of the material they are going to show – their solitary target is money.

Pu2.biz push notification.

Pop-up promotions itself is a very good, low-priced and also very efficient advertising method¹. It allows the vendor to attach the buyers’ attention to their site, and the buyers to get the dynamic updates on the goods they intend to buy. When the consumer will get a pop-up notification that the TV set he likes to purchase is available at the online shop he/she checked out earlier with a 15% price cut, one will surely use this opportunity and purchase it. Taking into consideration the extremely low price for the popups and their targeting, such a promotion and marketing method is a favourite thing amidst the marketing departments of huge online retailers.

Nonetheless, such a successful plan could not be missed by malware developers. Ability to show the popup advertisements by force to the victims of malware invasion is a perfect basis for malevolent manipulations with the popup ads. And Pu2.biz promotions is just one of hundreds that are “employed” in this system.

Here is a short summary for the Pu2.biz site

How have I got the Pu2.biz virus?

There are a number of ways of getting contaminated by the adware that create the Pu2.biz popups storm. A lion’s part of this computer virus incidents is after the freeware or cracked programs, that are distributed on the peering networks. Free software can also be downloaded from the main site, and the adware is presented as a legal bundled program.

There is no need to blame yourself. A number of individuals regularly work with the unreliable programs from untrusted sources: abandonware, different apps that are free, or even hacked programs. Every one of these types of software are risky, due to the fact that it is very simple to build in a Pu2.biz 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.

Pu2.biz popup malware can also be concealed in the advertisement somewhere on the strange web page. Such web pages are typically filled with colorful and blinking advertisements, and their owners often accept any promos to be posted on their web page. Therefore, clicking such banners is a risky thing: only the ad provider realizes what will occur when you click this advertisement. Besides some “light” viruses, like adware or undesirable programs, you can also receive something a lot more hazardous, like ransomware or coin miner; the big share of coin miners distribution is exactly after the malicious ads.

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

Potentially unwanted applications, like Pu2.biz popup virus can provoke a lot of different problems on your personal computer. Distracting is not the single effect – pop-up notifications may show you the promotions, where you are offered to get one more dubious program, or “a perfect security tool”. Scareware is usually spread with the last motto. Potentially undesirable applications, in turn, may have spyware functionality. And it is quite hard to distinguish the unwanted app from a legit one, if you don’t know the exact names. Besides the potentially unwanted programs and dubious antiviruses, popup-related ads are also exploited as a spreading method by different trojan viruses, for example – 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 clicking these promotions, they may be clicked by whoever who also makes use of 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 data and money loss. It is recommended to remove the viruses with antivirus programs as soon as possible.

How can I get rid of Pu2.biz pop-up advertisements?

The tutorial of Pu2.biz adware clearing contains 2 sections. First, we need to get rid of the malware, and after that correct the effects of its action. The removal process is very easy, due to the fact that it can be executed even with using Microsoft Defender – security program that is present on all personal computers with Windows 8/10. Nonetheless, as a result of its large resources consumption, as well as some failures that may be serious for some groups of individuals, Defender is frequently turned off by the users, so its use is probably impossible. What’s more, different trojan viruses are able to disable the embedded antivirus. It is far better to make use of the separated program that will not have such weakness.
