What are Pu5.biz pop-ups?

Quick reference

I hope this article has changed your mind: I believe that there is no one product or service that can give you more opportunities to sell your TV set than this one! I will make amends by saying that I am not endorsing any particular TV product or service in any way. But as part of an ongoing discussion about the need to increase the number of TV sets in existence, I would like to present my personal opinion of TV set management.

1. TV Set Management Is a Choice (The ‘Right’ Choice and the ‘Right’ Price)

Here are the main reasons TV Set Management has to be a choice. Firstly, they serve two purposes; to establish the highest possible sales potential where a TV set can be reasonably priced as well as to serve the best part of the customer base.

Pu5.biz popups are an effect of adware presence. Adware is a type of malware that shows you the pay-per-view of pay-per-click ads, which generates a significant amount of revenue for adware distributors. These advertisements might include sometimes shocking composition, or have a link to malevolent content/website, because adware maintainers have no reason to check the goodness of the material they are going to show – their single target is money.

Pop-up marketing itself is a very good, affordable and also extremely successful marketing instrument1. It allows the vendor to attach the customers’ attention to their website, and the buyers to get the dynamic updates on the goods they wish to purchase. When the customer will get a pop-up alert that the TV set he likes to purchase is provided at the online shop he/she saw earlier with a 15% price cut, one will certainly use this possibility and get it. Taking into consideration the extremely low cost for the popups and their targeting, such a marketing method is a favourite thing among the marketing departments of big online stores.

Nonetheless, such a successful scheme could not be missed by virus creators. Option to show the popup ads by force to the targets of malware attack is an excellent basis for evil-minded manipulations with the popup ads. And Pu5.biz ads is one of hundreds that are “employed” in this system.

Such sites are usually loaded with colorful and blinking ads, and their owners generally permit any kind of promos to be placed on their web page.

Besides some “light” viruses, like adware or undesirable programs, you may also get something much more unsafe, like ransomware or coin miner; the substantial share of coin miners distribution is exactly after the malicious advertisements.

And it is pretty hard to distinguish the undesirable app from a legit one, if you don’t know the exact names.
