Nusmash browser hijacker removal instructions
What is Nusmash?
Nusmash is a browser hijacker that promotes the nusmash.com address, a fake search engine. As a rule, apps of this type promote fake search engines by modifying some of the browser's settings. Additionally, they tend to be designed to gather various browsing-related information. It is known that users often download and install browser hijackers unknowingly, therefore, Nusmash and other apps of this type are categorized as potentially unwanted applications (PUAs).
Apps like Nusmash promote certain addresses by making changing browser's settings such as the address of a default search engine, homepage and new tab so that users would visit it when they open a browser, new tab and enter search queries into URL bar. Nusmash changes those addresses to nusmash.com - an address a fake search engine that provides results generated by Yahoo (redirects users to search.yahoo.com). In most cases users who have their browsers hijacked by apps like Nusmash cannot remove address of a fake search engine from the aforementioned settings uninstall that app from a browser and/or computer. Another problem with most browser hijackers is that they tend to be designed to collect data like IP addresses, geolocations, entered search queries, addresses of visited pages, etc. However, in some cases they are designed to gather sensitive data as well. The problem with it is that their developers could sell collected details to third parties (potentially cyber criminals) or misuse them to generate revenue in other ways. Therefore, users who have browser hijackers installed on their browsers and/or computers may encounter issues related online privacy, browsing safety, or even identity theft.

ProStreamsSearch, Dosearch Lite and GoIncognitoSearch are some examples of other PUAs that are classified as browser hijackers too. However, there are many other apps of this type. As a rule, their purpose is to promote some fake search engine and/or collect various information. Simply said, they are useless to their users and designed only to generate revenue for their developers.
How did Nusmash install on my computer?
Quite often browser hijackers and potentially unwanted applications of other types are distributed by integrating them in download or installation setups of other programs as additional offers. Simply said, they are distributed by using a method called "bundling". As a rule, offers to download and/or install additionally included apps can be declined. It can be done via settings like "Advanced", "Custom", "Manual" (or certain checkboxes) that are available in download and/or installation setups. However, not all users check (and change) those settings when they download and/or install programs. Therefore, they download and/or install PUAs as well. In some cases users download and/or install PUAs through deceptive advertisements - by clicking ads that are designed to execute certain scripts.
How to avoid installation of potentially unwanted applications?
It is not recommended to download files or programs via untrustworthy sources like torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, questionable websites, etc. They should be downloaded via direct download links and official, legitimate pages. Also, it is advised not leave "Custom", "Advanced" and other similar options (or checkboxes) in download and/or installation setups unchecked. It is common that they can be use to decline offers to downloaded and/or install unwanted apps. Furthermore, it is recommended not to trust (click) advertisements that are displayed on shady pages. It is because they tend to be designed to promote other untrustworthy/potentially malicious websites. Sometimes they can be designed to cause unwanted downloads, installations. Any unwanted, suspicious apps (extensions, add-ons or plug-ins) that are already installed on a browser should be removed. The same applies to programs of this kind that are installed on the operating system. If your computer is already infected with Nusmash, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
