CostItApp is a newly released adware program that can cause you all kinds of trouble and inconvenience. Indeed, this application will definitely hamper your browsing experience, so you should remove it once you notice its presence. On top of that, this application might promote links to unreliable content and keep tabs on your browsing habits. So, in short, that is what the application does. However, we will not give this application a free pass, and we will discuss it in greater detail so that you know what kind of program you are dealing with. So let us begin.

CostItApp is a versatile application that can display various forms of advertisements, which include, but are not limited to, coupons, pop-ups, and banners. Since the advertisements are promoted by unknown entities whose legitimacy cannot be confirmed, we regard CostItApp as an unreliable application. For the most part the ads are just intrusive and very irritating, but there is a slight possibility that your computer could become infected with more malicious software, such as adware, browser hijackers, and so on.

Now we should talk about the application's origins in order to understand CostItApp’s malicious roots. This application is based on the JustPlugIt engine developed by JustPlugIt Ltd. It can be suggested that the company is based in Tel Aviv, Israel, because the company's Terms of Use state that the company adheres to the laws of Israel and any disputes that may arise will be settled in Tel Aviv courts. The company has a promotional website, called, where anybody willing to pay can create their own adware programs. Indeed, the company has no control over the content that is promoted via their programs, and JustPlugIt Ltd is not liable if something were to happen to your computer or if you experience a financial loss. So, obviously, it would be very difficult to hold someone accountable for infecting your computer with malicious software that damaged your computer’s hardware.

In addition to that, CostItApp might collect information about your browsing preferences. Information such as "Your IP address, domain names, referring website addresses, and some online web browsing activity to deliver more relevant advertising" will be collected and sent for analysis to the clients — not the developers. The clients can analyze it and make changes to the ads to make them more appealing. In addition to that, they can share this information with other third parties, which is undesirable to say the least. So, as you can see, CostItApp does not have any advantages. There is no reason to keep this program, so we encourage you to remove it.

In conclusion, CostItApp is an adware program that will only cause you trouble. The ads will be annoying and intrusive. And let us not forget that they are supplied by an unknown entity or even several entities. There is a small possibility that your computer will become infected with malicious software that might be quite annoying and hard to uninstall. Furthermore, the program can collect and share non-personal information about you, and we think you do not support that, so we invite you to remove CostItApp and then run a scan of you computer using an antimalware tool just for good measure.
