removal by Ugnius Kiguolis - - | Type: Adware

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 Reimage Cleaner Intego 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].

Costmin virusCostmin virus injects advertisements into search results and also displays them as pop-ups or banners. These ads do not originate from sites the victim visits. Costmin ads are based on victim's browsing activities and can contain links to dangerous web pages.

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.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
