What are Puscomosca pop-ups?

Puscomosca popups are a result of adware presence. Adware is a kind of malware that suggests you the pay-per-view of pay-per-click ads, which produces a substantial volume of revenue for adware suppliers. These advertisements might consist of explicit material, or have a web link to malicious content/website, considering that adware maintainers have no reason to check the goodness of the content they are going to reveal – their single target is money.

Pop-up advertising itself is a very good, low-priced and really efficient advertising instrument¹. It enables the vendor to link the customers’ attention to their website, and the buyers to get the dynamic updates on the goods they want to purchase. When the person will receive a pop-up notification that the TV set he desires to buy is offered at the online shop he/she saw earlier with a 15% discount, one will undoubtedly use this chance and buy it. Taking into consideration the exceptionally low cost for the popups and their targeting, such a promotion and marketing instrument is a favourite thing amidst the marketing teams of large online stores.

Nonetheless, such a successful strategy could not be missed by malware developers. Option to demonstrate the popup advertisements by force to the targets of malware invasion is a great basis for malevolent tricks with the popup promotions. And Puscomosca.com promotions is just one of hundreds that are “employed” in this system.

There are a number of ways of becoming contaminated by the adware that trigger the Puscomosca popups storm. A lion’s part of this malware instances is after the free software or cracked programs, that are spread on the peering networks. Free software can additionally be downloaded from the main website, and the adware is supplied as a legal bundled program.

There is no need to blame yourself. A huge amount of people regularly use the dubious programs from untrusted sources: abandonware, various apps that are free, and even hacked programs. All of these types of software are unsafe, since it is very simple to build in a Puscomosca malware under the cover of part of the license hacking script, or as a component of the self-made algoritm inside of the Windows optimization tool.

Puscomosca popup virus may also be concealed in the ad somewhere on the unusual website. Such sites are usually packed with bright and blinking advertisements, and their owners typically accept any type of promotions to be published on their page. Thus, clicking such banners is a shot in the dark: only the advertisement provider knows what will occur when you click this ad. Besides some “light” viruses, like adware or undesirable programs, you can additionally get something far more damaging, like ransomware or coin miner; the big share of coin miners circulation is exactly after the malicious advertisements.

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

Potentially undesirable applications, like Puscomosca popup virus may provoke a lot of different problems on your PC. Distracting is not the single problem – pop-ups may show you the ads, where you are offered to get another unknown program, or “a perfect anti-malware tool”. Scareware is often distributed with the last slogun. Potentially undesirable programs, in turn, can have spyware functions. And it is very 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 spreading method by various trojan viruses, for example – 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 can be clicked by whoever 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 solve it without data and money loss. It is recommended to remove the viruses with anti-malware programs as soon as possible.
