If your computer screen gets flooded by pop-up ads, coupons, and best offers, chances are your computer has been infected with Big-Bonus adware. This ad-supported application has no other function than to make money for its creators. Do not believe for a second that it would be beneficial for you to click on these “best deals”; on the contrary, you might jeopardize your system’s security. Most people do not know about the potential dangers of having an adware program on-board and tend to leave them untouched. However, not only are these ads very annoying, but they may also lead to unreliable websites. The presence of this adware may also indicate that there are other malware threats as well on your computer. That is why it is important to remove Big-Bonus right now along with all the other infections that can be associated with it.

Big-Bonus is not a milestone in the industry of useless and potentially harmful application development. In fact, it is yet another adware from the Multiplug family. As all the other members of this family, including Awesome-Promos and HaggleDazzle, this adware program was also built on the JustPlugIt engine. Although this application has an official web page at, it is not available for download; no button, no link, nothing. But if you have experience with this adware family, you are not surprised at that.

As a matter of fact, another very suspicious trait around this adware is that it is distributed mainly in third-party installers, such as InstallRex. That is a notorious installer that may contain malware applications. As far as we know, Big-Bonus may come with among others. That is a well-known browser hijacker. If it is on your computer, you will definitely notice its presence as it will appear in your browsers. The more malware threats you have on your system, the more exposed you become to unreliable web content and malicious websites. What you can do in such a situation is that you delete Big-Bonus and run a full system malware scan to identify the other threats.

Big-Bonus is a useless application that promises you online shopping “without hurting your budget” by giving you “the ultimate advantage of comparing the nest deals, discounts, and promotions.” But you should not believe one word of that promotional mumbo-jumbo. In fact, it is simply a program that shows third-party ads while you are surfing the web. It is mainly annoying on shopping sites, of course. Since this adware may collect information about your browsing habits, it is likely that you will be introduced to targeted ads. However, you can never know which ad is trustworthy and which one belongs to cyber criminals in reality. Therefore, clicking on any of these ads would be a bad idea. In order to stop the flow, we advise you to remove Big-Bonus ASAP.

Because this adware application installs extensions to your browsers, it is not enough to uninstall it via Control Panel. You also need to take care of the browser extensions in Mozilla Firefox and Google Chrome manually. If you have no idea how to do that, please follow our guide below this article. Keep in mind that you can actually avoid such malware attacks if you have a reliable antimalware program installed. We believe that SpyHunter is a great choice, but you can find a number of trustworthy security tools on the web. Make your choice if you do not want to waste more time and money chasing malware infections by yourself.
