Logic Search browser hijacker removal instructions

What is Logic Search?

Logic Search is a potentially unwanted application (PUA), a browser hijacker which supposed to improve browsing experience (provide users with accurate search results and some other features). However, it is designed to promote a fake search engine (feed.logic-search.com) by changing browser's settings and gather various information. Usually people download and install browser hijackers (and other apps that are categorized as PUAs) unintentionally.

feed.logic-search.com browser hijacker

After installation Logic Search sets feed.logic-search.com as an address of a default search engine, homepage and new tab. It means that people who have Logic Search installed on a browser are forced to visit feed.logic-search.com when they enter search queries into URL bar, open a browser and new tab. If used, this fake search engine redirects users to search.yahoo.com. In other words, it does not generate any unique search results and displays results generated by Yahoo search engine. In most cases browser hijackers do not allow users to remove address of a fake search engine from the aforementioned settings unless they uninstall it. In this case feed.logic-search.com can be removed, changed to another address only after uninstalling Logic Search. However, it is not the only reason to uninstall any installed browser hijacker. In most cases apps of this type are designed collect various browsing-related and other data. For example, IP addresses, entered search queries, addresses of visited web pages, geolocations, etc. They may be designed to gather personal, sensitive details as well. Their developers usually sell collected data to third parties (potentially cyber criminals) who misuse it to generate revenue in other ways. To sum up, users of browsers that are hijacked by apps of this type may experience problems related to browsing safety, privacy, or even become victims of identity theft. Therefore, if there is some browser hijacker already installed on a browser and/or operating system, then it should be uninstalled as soon as possible.

There are many various browser hijackers, most of them are advertised as useful, legitimate applications. However, most of them do not deliver any value and are designed only to help their developers to generate revenue. Besides, their users are exposed at risk of various problems. Examples of other PUAs that are classified as browser hijackers too are Directions Tab, Delicious Online Recipes and Access Gov Docs Tab.

How did Logic Search install on my computer?

In most cases people download and/or install browser hijackers and other PUAs through download and/or installation setups of other software. It is common that apps of this type are included in setups as additional offers and information about it can be found in their settings like "Custom", "Advanced", "Manual". Not all people check and change those settings when they download and install programs. By leaving them unchanged they allow for PUAs to be downloaded or installed alongside with wanted software. This distribution method of PUAs is called "bundling". It is worthwhile to mention that unwanted downloads and installations can be caused by clicking deceptive advertisements too. Those ads cause it by running certain scripts.

How to avoid installation of potentially unwanted applications?

It is recommended to download software (and files) from official websites and via direct links. Third party downloaders, installers, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites and other similar channels should not be used. Quite often they are used as tools to distribute unwanted, potentially malicious software. Third party installers should not be trusted too. Also, we recommend to always check "Advanced", "Custom" and other settings of any download and installation setup. If they include offers to download and/or install unwanted software, then they should be declined before completing download and/or installation. Intrusive ads that are displayed on shady pages, if clicked, often redirect people to other, potentially malicious websites. It is worth mentioning that such ads might appear on legitimate pages too. If unwanted ads appear on most web pages and/or a browser opens shady pages by itself, then we recommend to check if there are any unwanted apps (extensions, add-ons or plug-ins) installed on it and remove them immediately. Software of this kind that is installed on the operating system should be removed too. If your computer is already infected with Logic Search, we recommend running a scan with Spyhunter for Windows to automatically eliminate this browser hijacker.
