How to remove the "Sqoo search engine" browser hijacker
Written by Tomas Meskauskas on
What kind of software is Sqoo search engine?
Sqoo search engine is the name of an extension that operates as a browser hijacker. This piece of software makes changes to browser settings in order to generate redirects that go through the sharesceral.uno and sqoo.co fake search engines. Additionally, this browser extension spies on users' browsing activity.
Sqoo search engine browser hijacker overview
On our test machine, the Sqoo extension assigned sharesceral.uno as the browser's default search engine, homepage, and new tab/window URL. Therefore, whenever we opened a new browser tab/window or entered a search query into the URL bar – it resulted in redirects to the sharesceral.uno website.
In the latter scenario, sharesceral.uno immediately redirected to sqoo.co – wherein the query was automatically entered into the page's search input field. After the search icon was clicked, sqoo.co redirected to the legitimate Yahoo search engine (search.yahoo.com). Note that redirect chains may differ since factors like user geolocation might impact them.
Fake search engines redirect to genuine Internet search websites, as they are incapable of generating search results. In the rare cases where the fake sites can provide search results – they are inaccurate and include sponsored, deceptive, and malicious content.
Browser-hijacking software commonly uses persistence-ensuring techniques to complicate its removal, thus preventing users from recovering their browsers.
The Sqoo search engine extension has data-tracking functionalities. Information of interest may include: visited URLs, viewed webpages, searched queries, Internet cookies, personally identifiable details, account log-in credentials, finance-related data, and so forth. The gathered information can then be shared with or sold to third-parties.
To summarize, software like sharesceral.uno can cause system infections, serious privacy issues, financial losses, and even lead to identity theft.

Browser hijacker examples
We have analyzed thousands of browser hijackers; Calendar New Tab, Bigoloo, Quotes Srch Tab – are merely a few examples of our latest finds.
Browser-hijacking software usually appears legitimate and offers useful functionalities. The features seldom work as advertised, and in most cases – they are utterly nonoperational. It must be mentioned that even if an extension or application works as indicated by its promotional material – that is not a guarantee of legitimacy or safety.
How did Sqoo search engine install on my computer?
Browser hijackers can have "official" promotional sites, and they are endorsed on scam webpages. Most users enter these pages through redirects generated by websites using rogue advertising networks, misspelled URLs, intrusive ads, spam browser notifications, or installed adware.
Browser-hijacking software can also be bundled with regular programs. The risk of unintentionally allowing bundled content into the device is increased by downloading from dubious channels (e.g., free file-hosting and third-party websites, P2P sharing networks, etc.) and by rushing through installation processes (e.g., skipping steps/sections, using "Easy/Express" settings, etc.).
Additionally, browser hijackers are proliferated by intrusive advertisements. Some of these adverts can be triggered (by being clicked) to perform downloads/installations without user consent.
How to avoid installation of browser hijackers?
We strongly recommend researching software before downloading/installing it. All downloads must be performed from official/verified sources. When installing, it is essential to read terms, explore possible options, use "Custom/Advanced" settings, and opt out of all additional apps, extensions, and so forth.
We advise caution while browsing since fraudulent and malicious online content usually appears legitimate. For example, while intrusive advertisements may look innocuous – they redirect to highly questionable sites (e.g., gambling, pornography, adult dating, etc.).
In case of continuous encounters with such ads/redirects, check the system and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with Sqoo search engine, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
