What is YellowMarkApp?

YellowMarkApp is a worthless application that you should never install on your computer. According to security experts, it’s a genuine adware and a potentially unwanted program (PUP) that can offer none of the useful services at all. Its promises to enable comparison shopping, keep the users informed about the best deals and discounts, keep them connected to the valuable coupons, promo codes, etc. are bogus. That’s a marketing strategy that is used to convince people that YellowMarkApp is a reliable add-on. Nonetheless, you have to keep in mind that it’s a multiplug adware that solely seeks to advertise affiliate websites and earn easy money from advertising. First of all, it may show up on your computer out of nowhere and the first sign that will warn you about its presence is pop-ups, banners, in-text links, and other forms of ads on every corner of your computer’s screen. Usually, people think at first that ‘Ads by YellowMarkApp’ are brought by the websites that they visit. However, in reality they are powered by third parties and usually linked to affiliate domains. Many people have already reported that clicking on the YellowMarkApp ads made them visit really questionable websites, for example, offering to install additional software or update Java, Flash Player, and similar apps. Beware because YellowMarkApp redirects can even reroute to potentially dangerous websites and trick you into installing other potentially unwanted programs, such as adwares, browser hijackers and so on. Unfortunately, this app can not only disrupt your browsing experience by delivering misleading content but may also interfere with your privacy by installing cookies and accumulating information related to your browsing habits. Gathered information includes IP address, PC’s location, email address, search terms, mostly visited websites, data entered in them, clicks, and so. If such data would be used for improving the service only, then there would be nothing to worry about. Nevertheless, YellowMarkApp adware uses cookies and collects data with an intention to transmit/sell it to other third parties, which may have serious consequences. Thus, of you started suspecting that it is already running on your PC, we recommend checking the system with a reputable anti-spyware like, for instance, Reimage.

How can YellowMarkApp hijack my computer?

YellowMarkApp adware has rooted from a huge family of multiplug adwares, which includes such members as Pricora, Web Flipper, My Coupon Buddy, and so on. Likewise its counterparts, this adware mainly spreads via software bundles alongside other third-party software, such as download managers or media players. Thus, if you want to prevent its infiltration, you should carefully check whether the freeware that you opt for installing carries ‘optional downloads’ or not. For that, always select Advanced/Custom installation option and monitor the entire process step-by-step. The most important thing is to detect ‘additional components’ and unmark ticks saying that you agree to install each of them.
