Danger level 7
Type: Adware
Common infection symptoms:
  • Annoying Pop-up's
  • Shows commercial adverts


TopFlix is posing as a useful application that enables users to access region-locked content mostly focusing on internet TV platforms. Of course, it is a nice cover story; however, the sad truth is that this application modifies your DNS settings not to provide you access to the locked content sites, but, instead, to annoy you with third-party ads through your browsers. Unfortunately, these advertisements may be potentially unreliable. This means that if you click on them, you may be redirected to websites with questionable content and intention. If you do not want to figure out the hard way what may happen if you engage with a malicious website, we recommend that you delete TopFlix right away. Another bit of bad news about finding this adware program on your computer is that it is quite possible that it was not alone when it entered your system. Therefore, you also need to make sure that you clean all potential threats from your computer before you can feel secure in your virtual world again.

This useless application has a promotional page at topflix.info, but apart from some pieces of information and a contact form, you will not find anything useful there. In fact, you cannot even download this supposedly useful program. This is quite suspicious and also makes you wonder how on earth can this adware end up on your computer then? As a matter of fact, we are not at all surprised by this because most adware programs usually use freeware bundles to spread on the Internet. However, this can mean that such bundles are packed with a number of malware threats. Therefore, if you install one, it is possible that you will find adware programs, browser hijacker, and potentially unwanted programs as well on your computer.

Most computer users do not even realize that they infect their own system by downloading such bundles from unfamiliar and suspicious file-sharing websites. This can happen when you are searching the web for anything free, including books, movies, and programs. Your search results will most probably include a great number of fake and malicious websites run by schemers. If you are not experienced enough, you may think that finally you have found a place to download what you are looking for. But, instead, you will most likely download an infected bundle and let several malicious software installers onto your machine. Sooner or later you realize that there are more and more annoying third-party ads in your browsers whenever you go surfing the web, or you find an unfamiliar search page as your home page and so on. That is why you need to be extra careful when downloading free tools. Visiting questionable websites may result in infecting your computer. If you have landed on such sites recently, we advise you to remove TopFlix and run a full-system malware scan to see if any other malware infection has found its way to your computer.

We have discovered that this adware is identical to DNS Unlocker and CloudGuard applications. This program acts as a VPN/DNS manager that is supposed to help users to watch region-locked content on popular internet TV platforms, including NetFlix, Spotify, and HBO. By modifying your DNS settings, this infection can show third-party commercial advertisements, pop-up ads in all major browsers, because it reroutes the web traffic through his own DNS and thus can insert advertisements. In order to modify the DNS settings, it uses a task with a powershell script. This task has a random name, which looks similar to this: "{7E087947-0A0C-0B0A-7811-780804041108}." There is a command inside this task that launches powershell with a long line of code that is encoded with Base64 encryption. Here is what the Terms of Service discloses about the third-party content you may be introduced to by using this program:

The Services may contain links to other web sites, as well as text, graphics, pictures, designs, video, audio, information, applications, offers and other content derived from third parties (collectively "Third Party Content"). Such Third Party Content are not supervised, endorsed, monitored or reviewed by us for accuracy, appropriateness, compliance with any applicable laws or regulations, or completeness, and we are not responsible for any Third Party Content…

This excerpt clearly shows that you should not trust any of the advertisements coming from this adware. It is also possible that this adware can spy on you and collect data about your browsing habits, etc. This is how you may find relevant ads on your screen after some time. We advise you to stay away from these third-party ads because they may simply be used as bait to lure you onto malicious websites. Landing on unsafe websites has a price you may not want to pay. You may easily end up with even more malware infections on your computer or get scammed out of your money. If you want to feel safe, you should delete TopFlix ASAP.

So here is what you can do to get rid of this annoying threat. Fortunately, this adware has a working uninstaller, which makes everything easier for you. Locate the uninstaller through Control Panel and run it. It should leave no leftovers. But the DNS settings still need to be fixed manually. We have included step-by-step instructions below in order to assist you with the required steps. Even if you do not consider yourself an experienced computer user, you may be able to accomplish this mission by using our guide. However, if you are looking for a powerful solution to defend your PC from similar malware attacks, we suggest that you use a reliable anti-malware program.
