How does QuantumCoupons work?

At first glance, this program’s purpose seems to provide you with discount coupons “for your Favorite Brands & Stores” according to its website. However, nothing could be farther from the truth as you will not see any discount coupons whatsoever. Yet this application is prone to subject you to commercial content, and it displays it in the most annoying manner possible. Our researchers say that QuantumCoupons can render window dedicated to promoting certain websites, such as http://musicrule.com/choose.php. You can close this window, but it will open continuously during your Windows session. In addition to that, this application will make changes to Internet Explorer and open it without your authorization and load promoted websites, such as http://freebiesfrenzy.com. If you find these advertising practices unwelcome, then you might want to get rid of this application especially since it can jeopardize your system’s security.

According to our researchers, the promotional links displayed by this application are not region-specific. So they must be controlled directly by this program’s owners. Therefore, the owners can configure this program to promote anything they want, and it might include malicious software and other questionable content. You might be subjected to suspicious websites that require that you enter your email address to access particular content. As a direct consequence of this, you may start receiving email spam which might contain Trojans. In some cases, you may be offered to download PC optimization software which might ask you to purchase it, but it will not work after the purchase has been made. In short, there are many things that can happen while having QuantumCoupons on your system.

Where does QuantumCoupons come from?

This adware comes from the same group of developers that are responsible for creating similar programs such as BabyMegs, Own Dates, Diet Bright, and many others. This developer has released dozens of similar applications in an effort to make as much money as possible. Also, they need to release new applications all of the time because the databases of anti-malware program’s such as SpyHunter are frequently updated to delete and prevent malware from entering your computer. An anti-malware program is the first line of defense against unwanted and malicious software which often poses as legitimate such as in the case of QuantumCoupons and its clones.

Nevertheless, safe browsing practices are also essential. Therefore, we want to inform you about QuantumCoupons’s dissemination methods. Our researchers have found two methods used to disseminate this adware. Firstly, its dedicated distribution website Guantumcoupons.com is promoted by browser hijackers that include the link to this site in their search results. Guantumcoupons.com hosts this adware’s InstallCore-based installer known to contain potentially unwanted programs, adware, and browser hijackers that are installed along with QuantumCoupons. The second method involves bundling this program with other usually legitimate freeware and put the bundle up for download on various shady freeware distributing websites. So, if you download software from third-party websites make sure to check them for additional programs by opting for advanced installation settings because, in many cases, additional software is purposefully hidden from plain sight.
