CostMin – a virus which is still active and can cause a serious havoc

CostMin is an adware-type program which is responsible for displaying sponsored notifications on different websites. Typically, these ads are labeled as “Ads by CostMin,” “RocketTab powered by CostMin,” “Powered by CostMin,“ “Ads powered by CostMin,“ “Brought to you by CostMin,“ etc. If you have been suffering from such pop-up ads for a while, you need to search your computer for a potentially unwanted program which was found in 2015. However, our experts decided to repeat the research of this adware[1] and found it to be capable of tracking its users[2] and causing other issues. To start with, it’s important to stress the fact that the adware is distributed with the help of bundling, what means that people can download this app unintentionally along with another free software. That’s why it has been listed as a PUP and is sometimes even considered to be a virus. In addition, people are not directly informed about CostMin ads and that not all of them can be trusted. Close analysis of the app has shown that almost each of its the ads is sponsored, what means that they are prepared by third parties who may have suspicious intentions. Keeping in mind the fact that these ads can make you visit unreliable websites, we would recommend you to remove CostMin. It can also hide under the CouponSupport name.

Examples of Costmin ads 

The main reason why users are bothered by these ads is a desire to promote affiliate sites which are trying to increase their popularity. However, you cannot be sure that each of these websites is safe. Besides, we would also like to draw your attention to the fact that CostMin virus uses cookies to know more about its victim. As soon as it settles down on a target system, it not only corrupts registries, Windows startup, and settings on each web browser. It can also activate tracking cookies and start collecting information about user’s web browsing habits. There is no doubt that there are lots of people who are not keen on sharing PC’s location, email address[3], search queries, web pages viewed, and similar information with third parties, so if you are one of them, we would recommend installing Reimage and running a full system scan with it. This way, you will take care of CostMin removal from the system and will ensure its full protection. NOTE: don’t forget to update your anti-spyware regularly[4].

How can I avoid this adware?

CostMin can by avoided by monitoring installation of every download you make. Make sure you start reading the Privacy Policy, End User’s Agreement, and similar information before clicking the “Download” button and installing a specific program. Then, you need to check every window which is displayed to you during the installation of the program. Usually, you need to unmark the check box claiming that you want to install additional components on your system. For that, you should always choose “Custom” or “Advanced” installation methods because it’s the only way to see these check boxes. We highly recommend being very careful when downloading Zoom Downloader, Superfish, Window Shopper, Yontoo and FB Photo Zoom applications because they have been known to be related to this adware. If this program enters the system, it can easily hijack[5] each of your web browsers, change their settings and then start displaying its ads as soon as you enter your favorite website.

CostMin removal procedure

In case this adware already ended up on your PC’s system, you should not wait until it starts causing issues like redirects, slowdowns, and advertising. To get rid of these inconveniences, you need to follow manual removal guidelines that are given down below or remove CostMin virus with the help of professional software. Programs that we recommend using are given below. However, make sure you update them before running a full system scan to be sure that all components of this adware and other adware-type apps that you might have installed on your computer along are eliminated. If you are not willing to use automatic uninstall option, you can always follow manual removal guide prepared to you by 2-spyware experts.
