0sntp7dnrr is an unwanted software app of the browser-hijacking family that can get attached to Edge, Chrome, Firefox, and other browsers. Once installed, 0sntp7dnrr forces the browser to display ads and to automatically send the user to sites that need a boost in their traffic.

Symptoms Different kinds of ads in your browser as well as unwanted modifications in the browser’s settings are the symptoms that you can expect from a hijacker.

The 0sntp7dnrr Virus will redirect your browser searches.

A browser hijacker is basically an app created to promote different sites, services, and products by getting more and more users exposed to them. Adware apps are similar to browser hijackers, but the main difference is that a hijacker, in addition to the ads it shows, will also change the search engine or the homepage of the browser, which further helps push its advertising agenda.

Browser hijackers like are one of the most commonly encountered forms of potentially unwanted software and even though they do not damage the systems they get installed on and cannot be categorized as viruses, they are still quite unpleasant to have on one’s computer.

One of the main differences between browser hijackers like 0sntp7dnrr and more serious computer hazards like Trojan Horses or Ransomware infections is that the former, unlike the latter, do not try to keep their presence in the system undetected. In fact, it is quite the contrary – since browser hijackers are designed to advertise from inside the user’s browser, their job is, in a way, to be as noticeable as possible. This is why you will likely constantly keep seeing various ads, pop-ups, and clickbait links on your screen while you are trying to browse the Internet. Furthermore, since hijackers earn money for their creators on a Pay-Per-Click or Pay-Per-View basis, they need you to interact with the ads and visit the sites promoted by the unwanted app, which is why the advertisements would likely pop up on the most inconvenient of places on your screen. An example of that is when you are watching an online video or reading through an article and some obnoxious banner is displayed right over the video/article, forcing you to click on the banner before you can continue watching/reading.

What are some dangers related to browser hijackers?

Even though the app you currently have on your hands isn’t a particularly dangerous piece of software, you must realize that it is still not something we would advise you to trust and keep on your computer.

One of the potential dangers that could come from hijackers is in the form of the questionable clickbait ads that applications like 0sntp7dnrr might show to users. Not all online advertisements are linked to legitimate and reliable sites and some of them might even originate from phishing pages or from sites hosted by hackers and used for spreading malware and getting gullible and inexperienced users infected.

In addition, some hijackers are known for using deceitful advertising tactics such as lying to you about malware in your computer in order to get you to buy a software security product advertised by them. Oftentimes users fall for this kind of scam and end up buying products they don’t really need because a hijacker app has misled them. All in all, it is best to uninstall 0sntp7dnrr and our removal guide will help you do that in a quick and safe fashion.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
