How to uninstall the Logic Search browser hijacker

What is Logic Search?

Logic Search is a potentially unwanted application (PUA), a browser hijacker supposedly designed to improve the browsing experience (provide accurate search results and other features). In fact, it promotes a fake search engine (feed.logic-search.com) by changing browser settings and gathering various information.

People usually download and install browser hijackers (and other apps categorized as PUAs) unintentionally.

After installation, Logic Search sets feed.logic-search.com as the address of the default search engine, homepage, and new tab. Therefore, people who have Logic Search installed on their browsers are forced to visit feed.logic-search.com when they enter search queries into the URL bar, open a browser and new tab.

If used, this fake search engine simply redirects to search.yahoo.com - it generates no unique results and displays those generated by the Yahoo search engine. In most cases, browser hijackers prevent users from removing the address of a fake search engine from the aforementioned settings, unless they uninstall the rogue software.

In this case, feed.logic-search.com can be removed and the setting assigned to another address only after uninstalling Logic Search. This, however, it is not the only reason to uninstall installed browser hijackers. In most cases, apps of this type collect browsing-related, and other, data.

For example, IP addresses, entered search queries, addresses of visited web pages, geolocations, etc. They might also be designed to gather personal, sensitive details. Developers sell the data to third parties (potentially, cyber criminals) who misuse it to generate revenue in other ways.

In summary, users of browsers that are hijacked by these apps might experience problems relating to browsing safety/privacy or even become victims of identity theft. Therefore, remove all browser hijackers that are already installed on the browser or operating system immediately.

Browser hijackers are advertised as useful, legitimate applications, however, most deliver no value and simply help the developers to generate revenue. Furthermore, users are exposed to risk of various problems. Examples of other PUAs that are classified as browser hijackers include Directions Tab, Delicious Online Recipes and Access Gov Docs Tab.

How did Logic Search install on my computer?

In most cases, people download and install browser hijackers, and other PUAs, through the download/installation set-ups of other software. These apps are often included into the set-ups as "additional offers" and related information can be found in settings such as "Custom", "Advanced", and "Manual".

Many people fail to check and change these settings when they download and install programs, thereby allowing PUAs to be downloaded and installed together with regular software. This PUA distribution method is called "bundling". Note that unwanted downloads and installations can be also caused by clicking deceptive advertisements that run certain scripts.

How to avoid installation of potentially unwanted applications

You are advised 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 - they are used to distribute unwanted, potentially malicious software.

Third party installers should not be trusted. Check "Advanced", "Custom" and other settings of all download and installation setups. Dismiss any offers to download or install unwanted software before completing the process. Do not click intrusive ads that are displayed on dubious web pages, since they can redirect to other, potentially malicious websites.

These ads might also appear on legitimate sites. If unwanted ads appear on most/all web pages or the browser opens dubious pages automatically, check for installed unwanted apps (extensions, add-ons, plug-ins) and remove them immediately. Also remove software of this kind that is installed on the operating system.

If your computer is already infected with Logic Search, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
