In case you believe that an app, called YellowMarkApp is suitable to improve your browsing experience, don’t be misled – it may just do the opposite. Security researchers classify YellowMarkApp as an ad-driven unwanted program or a PUP and recommend the deletion of it from your machine. Most users report that it also may rely on a browser extension to display interruptive ads and collect information.
Did You Know How YellowMarkApp Got In Your PC?
There are many possible ways this app may have gotten in your PC. One of them is by clicking on an ad on a website that may have redirected you to a third party location promoting the adding of the app to your computer. Another way is by installing a free program. As unlikely as it seems, free software providers often bundle third-party apps, such as YelloMarkApp for example with the purpose of generating profits most likely as a part of an affiliate deal.
What Does YellowMarkApp Do?
Usually, PUPs such as this one are created for a sole purpose – generating money for their owners. They often may exhibit the same behavior that is displaying ads in the form of pop-ups, modified site content (highlighted text), ad-supported search results, advertisements on the website’s ad spaces, etc. Some which are more cunning may display ads outside of the browser environment. Besides the most likely slowing down of the PC they affect, another interesting detail about those apps is that they may collect different information with the goal to implement the so-called ‘behavioral advertising’ method. When we dissect behavioral advertising we will eventually come to the conclusion that the app may employ beacons, LSOs (Local Shared Objects or Flash Cookies) and other technologies. This is done order to examine which are the top sought words by you, the user. Based on those, it will begin to display advertisements accordingly.
More so, YellowMarkApp may display ads, leading to third-party sites that most of us know that may conceal anything – from more adware, through scams to malware. Most scams connected with such sites may rope users into entering their personal information as a part of website registrations, surveys or other fraudulent promotions and prize claims.
