This is a common, quite ordinary unwanted ad-supported soft that is linked to the trivago.com travel site by means of an affiliate program. It means that the site itself is, actually speaking, more or less legitimate, but the partners program they initiated brought some crooks that took advantage of it: in order to bring traffic and get paid, this pop-ups adware was designed. Thus, it maximizes the revenue based on traffic by means of aggressive redirects and intrusive pop-ups with ads. Although it’s not considered too dangerous in an explicit way, it’s highly desired to clean your system up of such a harassing PUP.
You may come across with the nasty adware thanks to an email bomb – a spam that could have attached the trivago.com pop-ups infection. For sure, there can be lots of different possibilities: shady visits to sites that prefer to their good reputation, ill methods of retrieving money. Otherwise said, one may get this adware or any other from untrustworthy sites. Also, the bundle freeware may cause you this adware infiltration.
Once the infiltration occurred, the victimized users will find a freshly appeared shortcut on their desktops. Another sign that you’ve been hacked is the annoying invasion of online advertisement promoting some dream places to go on holiday. The redirection tendency to the already mentioned Trivago site isn’t the one and only danger to worry about; the issue lies in the so-called mal advertising (or malvertising, from “malicious advertising”): cyber criminals use this type of hijackers to expose your computer to greater threats, such as Trojans and ransomware.
