Pop-up marketing itself is a good, affordable and also really effective marketing solution¹. It makes it possible for the vendor to link the buyers’ interest to their website, and the customers to receive the dynamic updates on the goods they wish to purchase.

A lion’s part of this virus instances is after the free software or cracked programs, that are distributed on the peering networks. Free software may additionally be downloaded from the main site, and the adware is supplied as a legal bundled program.

There is no need to blame yourself. A huge amount of individuals frequently work with the uncertain programs from untrusted providers: abandonware, different tools that are free of cost, and even hacked programs. Every one of these kinds of applications are unsafe, because it is extremely easy to integrate a Re04.biz 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.

Re04.biz popup virus may also be hidden in the advertisement somewhere on the unusual web page. Such web pages are usually filled with intense and blinking advertisements, and their owners often accept any kind of promotions to be posted on their page. Hence, clicking on such banners is a shot in the dark: only the ad provider realizes what will occur when you press this ad. Besides some “light” viruses, like adware or unwanted programs, you may likewise get something much more dangerous, like ransomware or coin miner; the large share of coin miners circulation is exactly after the malicious ads.

Scareware is often distributed under the last motto. Potentially unwanted applications, in turn, may have spyware functions. 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 banners are also chosen as a distribution method by various trojan viruses, for instance – coin miners. The consequences of activity of such malware is 100% unpleasant, and can cost you hundreds or even thousands of dollars. And even if you are not tapping these banners, they may be clicked by whoever who also makes use of your PC – parents, children, spouse, etc. So the things can become much more serious, and it will be much harder to solve it without data and money loss.
