How does Setupsk work?

Setupsk might slither into your operating system silently, or you could be tricked into installing it yourself. If you have no idea where this adware has come from, the chances are that you interacted with an unreliable installer that hid the advertising-supported program behind other, more attractive programs. If you were introduced to this adware via pop-up offers, advertisements, unreliable websites, or third-party installers, it is likely that it came bundled with other programs as well. So, it is likely that other suspicious pieces of software are active on your operating system. Even if they look harmless, you have to inspect them, and the best tool for that is a legitimate malware scanner that is up-to-date. Note that if you use outdated, unreliable scanners, it is unlikely that you will get 100% accurate scan results. What should you do if this tool detects much more dangerous threats than Setupsk? If that is the case, and you want to delete them manually, you need to research and remove them first. In this situation, the adware has to wait, and that is not an ideal situation.

In order to showcase advertisements, Setupsk injects traffic by from 80 to 24681 and from 443 to 24136 ports. By doing this, the adware ensures that ads are injected on every page that the user visits. Our research team has found that the program evades,, and IPs, and it has white-listed a bunch of websites, most of which are Russian. Some of them include,,, and It was also found that Setupsk silently connects to a bunch of different servers, one of which represents a content monetization system, which proves that the creator of this adware is earning money for the ads it displays. Of course, the parties using this adware to showcase their deals are unknown, which is why interacting with any of the ads is dangerous. If you have done this already, think if maybe you have downloaded malware or disclosed private information. Maybe you can take some steps to rectify the issue (e.g., delete malware and call the bank to discuss the protection of your accounts). Overall, the most important thing you can do is delete the adware because that is the only way to stop the suspicious advertisements.
