Our goal within the next lines will be to help you deal with an annoying software component for browsers like Chrome and Firefox by removing it from your system in case it is causing disruptions while you are browsing the Internet. Some of the “abilities” of this app is to redirect the users to various pages on the Internet and to show ads in their browsers. Additionally, it may install a new search engine service in the browser, replacing the previous one, as well as change the address of the homepage and the address of the new-tab page. It is likely that these changes would be advertised as useful for the user. In fact, the whole Mobnootiffy tool is probably going to be promoted as a useful add-on for the browser that would make one’s web experience more pleasant and safer. However, one thing to note here is that the changes may be quite invasive and you may not be able to opt-out of them or to cancel them once they have been imposed unless the whole Mobnootiffy tool gets uninstalled. Also, the random popping-up of ads, banners and page-redirects on your screen while you are trying to find something on the Internet could also be quite irritating, to say the least. Not to mention that the new search engine or the homepage that has been set as default on your browser by the annoying app are likely not going to be anywhere as useful as advertised. In fact, they may make it quite more difficult for you to actually find what you are looking for on the Internet. All of this leads us to the conclusion that Mobnootiffy “Virus” is nothing more than another representative of the well-known category of potentially unwanted software known as browser hijackers. In case you’d like to find help with removing the hijacker, you can find it in the following list of instructions.

Mobnootiffy “Virus”

One more thing…

A very important aspect regarding the apps of the browser hijacker category is that, while they are not as dangerous as Trojans, Ransomware and other similar infections, they are not software that we would advise you to put your trust it. The issue here is that you won’t really have a say in what advertising and commercial content gets brought to your screen by the hijacker. Usually, such apps try to access your browser history and cookies and determine what ads you may be interested in but there’s nothing to say that the algorithm of the hijacker won’t determine that you need to be presented with ads from unreliable sources. And if this happens and you click on some sketchy ad that is linked to a dangerous site, you could get all kinds of nasty infections and malware in your computer. We already mentioned the Ransomware and the Trojan Horse threats but you should know that these are only two examples of the many malware programs that you could encounter if you are not careful with what content you interact with while online.

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
a professional malware removal tool.
