How to remove the Dosearch Lite browser hijacker

What is Dosearch Lite?

The Dosearch Lite browser hijacker promotes tailsearch.com, a fake search engine. Typically, browser hijackers promote these addresses by making certain changes to browser settings. Dosearch Lite also gathers data relating to users' browsing habits.

Typically, users download and install browser hijackers inadvertently, and therefore, apps such as Dosearch Lite are classified as potentially unwanted applications (PUAs).

Browser hijacking apps promote fake search engines by modifying certain browser settings. Typically, the address of the default search engine, homepage, and new tab. In fact, Dosearch Lite does not actually change these addresses to tailsearch.com, however, it detects when users enter search queries into the URL bar and redirects them to tailsearch.com anyway.

Depending on the geolocations of its visitors, tailsearch.com redirects them to google.com or bing.com (via my-search.com and search-checker.com, and other dubious addresses). In summary, tailsearch.com does not generate any unique results, and simply provides results generated by Yahoo or Bing.

Note that a hijacked browser can be stopped from causing redirects to a specific address only by uninstalling the app that has hijacked it. In this particular case, tailsearch.com can be stopped from being opened by uninstalling Dosearch Lite (or other app designed promote this address).

Browser hijackers also gather various information relating to users' browsing activities, and other details. For example, addresses of visited pages, entered search queries, geolocations, IP addresses, etc. Also, private, sensitive information.

Developers sell the data to third parties (potentially, cyber criminals) who misuse it to generate revenue. Users with browsers hijacked by apps such as Fantasic Movies might thus become victims of identity theft, experience problems relating to privacy and browsing safety, and other issues.

Therefore, any installed software of this type should be removed from browsers/computers as soon as possible.

There are many browser hijackers on the internet. Some more examples are StreamSearchFinder, GoIncognitoSearch and VideoSearchNet. Typically, they are advertised as apps that supposedly improve the browsing experience (include various features, generate accurate search results, etc.) and are useful in other ways.

In fact, they are designed only to modify browser settings and gather information. I.e., they are useless to regular users and can cause serious issues.

How did Dosearch Lite install on my computer?

PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling". By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices.

Intrusive advertisements proliferate PUAs as well. When clicked, the ads can execute scripts to download/install these applications without users' permission. Some PUAs have "official" download web pages from which they can be downloaded.

How to avoid installation of potentially unwanted applications?

You are advised to download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.

Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations. Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from the operating system.

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