YellowMarkApp is a new member in the Multiplug adware family that is not at all welcomed due to the potentially harmful traits it exhibits. This is a totally useless application that might be detrimental to the health and security of your computer. Please believe us when we say that it is not enough to close these ads. They will constantly come back again and again like they have an infinite source. These third-party commercials can completely ruin your browsing experience by disrupting your surfing and littering your screen. But, in fact, that is just the tip of the iceberg. You might be exposed to unsafe third-party content once you click on the ads. There are a number of reasons why we think that it is best to remove YellowMarkApp from your computer if you care about your virtual security. At the end of our article we will share with you how you can do that, but, first, let us see the whys.

YellowMarkApp has no real benefit or function for you; this is a simple ad-supported program that was built on the JustPlugIt engine like hundreds of other applications, including DealForUse and WorldWideCoupon. This adware was also designed to make money for its developers. Since they get paid by the number of clicks on the ads the application displays while you are browsing the web, it is in their best interest to make sure you click. How do they do that? Well, imagine seeing advertisements, best deals, and offers that totally match your taste or your current wishes for products. Most people would not think for a second, just click on the ad that feels like “yes, that is what I need now"; and that would be a wrong move. Do you know why? It is because you can never be certain that the link in the ad is not corrupted. It may be embedded by schemers who can exploit this adware in order to redirect unsuspecting users onto their malicious websites. These criminals have a variety of ways to scam you. If you do not want to end up in their crosshairs, you had better delete YellowMarkApp as soon as possible.

This adware application cannot be downloaded from its official website, since there is none. That already tells you a lot about the reliability of this program. Obviously, the people behind YellowMarkApp want to spread this adware over the net in a way that will get it to as many users as possible. What is the easiest and most frequently used distribution method for adware and other infections? If you think “freeware bundles," you are right. Lots of users download free software every day. That is why there are a great many unsafe freeware websites that promote installers that may be packed with malware infections. Clicking on the wrong button or link on such a website may result in more infections on your computer. If you want to keep your system safe, we advise you to remove YellowMarkApp and scan your PC for other threats.

The removal of YellowMarkApp is not too complicated, but also not as simple as uninstalling the application via Control Panel. The thing is that although the browser extension will disappear from Internet Explorer, the Mozilla Firefox and Google Chrome extensions have to be dealt with manually. In order to assist you with the essential steps, we have added instructions below the article. It is also worth using a reliable online scanner to check for the presence of other threats on your computer so that you can eliminate all infections, and thus restore your system’s security. If the scan returns with several issues, it may be time to protect your computer with a professional antimalware tool.
