Iiiu.xyz Removal Guide

What is Iiiu.xyz?

Iiiu.xyz is a homepage address that is set on the installed web browsers as soon as the potentially unwanted program from QxSearch is installed

Iiiu.xyz by QxSearch Inc.Iiiu.xyz is a browser hijacker that was developed by a well-known PUP producer QxSearch Inc.

Iiiu.xyz is a potentially unwanted program that specializes in a full takeover of the installed web browsers. Unlike genuine applications, this browser hijacker is usually installed without asking for users' permission and initiates settings changes on Google Chrome, Safari, Internet Explorer, Mozilla Firefox, and other browsers. This way, the search engine is replaced by a customized one, and the homepage, as well as the new tab address, is swapped to Iiiu.xyz.

Upon typing and looking for a search query, users are then redirected to hxxps://iiiu.xyz/results.php?wd=, where they can see multiple sponsored links at the top instead of organic search results that other engines like google.com or bing.com would present. Additionally, Iiiu.xyz is known to gather several types of information about users' web browsing habits to spam them with targeted ads.[1]

Name Iiiu.xyz
Type Browser hijacker
Category Potentially unwanted program
Developer QxSearch Inc.
Installation Users typically install a potentially unwanted program via bundles software packages without realizing it. In other cases, the app may be installed deliberately without fully knowing its functionality
  • New tab address, homepage, and search engine are set to Iiiu.xyz
  • Search results are littered with sponsored links that may not always be accurate or even safe
  • Increased amount of ads on all sites that you visit
  • Slow operation of the web browser
  • Additional browser extensions or applications installed on the machine without permission (this is due to software bundling, as multiple apps may be deceptively offered within one installer)
Risks Users may be led to potentially dangerous sites that incorporate phishing, scam or other deceptive techniques in order to acquire their personal information or make them install bogus applications
Detections Virus Total report shows that one engine marks the site as “Phishing”
Termination Browser hijackers are relatively easy to remove – simply follow our guide below this article; nevertheless, it is always recommended to scan your machine with anti-malware software (such as FortectIntego) to make sure that no other malicious software is present

Iiiu.xyz does not only influence which websites users visit but may also lead them to places that are deemed inappropriate or even dangerous from a security point of view (scam, phishing). Therefore, it is better to get rid of the potentially unwanted program developed by QxSearch Inc. and revert the web browser modifications.

As a general rule, browser hijackers are not considered to be a major security threat, so calling the PUP “Iiiu.xyz virus” is quite a bit of an exaggeration (viruses infect internal OS files and propagate further that way, hijackers do not possess such functions).[2] However, as users' online complaints and security scandals that relate to high-profile organizations piling crapware into brand new laptops[3] show, unwanted programs may also be a huge cause of concern.

QxSearch, the developer of the Iiiu.xyz browser hijacker has other multiple PUP releases, including:

Such companies are leading a successful business, all by installing unwanted applications on unsuspecting users' computers and exposing them to sponsored content. Nevertheless, users sometimes may struggle with Iiiu.xyz removal, as not many are happy with web browser changes that result in web surfing difficulties.

Iiiu.xyz hijackIiiu.xyz is a website that gets established on the hijacked web browsers as soon as the potentially unwanted program is installed

The main problem with browser hijackers like Iiiu.xyz is that their usability and benefits are highly questionable, as reputable search engines can do the job much better, without interrupting web browsing activities with ads and, while both parties collect browsing data, high-profile companies like Google can be trusted with it.

To remove Iiiu.xyz hijack, you will have to locate the unwanted program that is located on your Windows or Mac computer and uninstall it. Check out the instructions below. If you are still having trouble, you can get rid of the unwanted app with the help of security software such as FortectIntego.

Watch out for optional components inserted into the installation wizards

In most of the cases, users are exposed to deceptive behavior of software installers when they download them from third-party websites. While many sites that host applications do have certain security procedures in order to prevent malware from being distributed on their sites, it does not mean that they do not try to insert and adware or a browser hijacker into your machine – and they do it in a manner that is not considered fair.

A lot of times, software installers are filled with optional installs, and the developers or third-party sites try to hide them from users' eyes deliberately. Of course, a major role is also played by users as well, as they are the ones that do not look at the installation process carefully. However, software bundling practices are long known to be unfair and also sometimes result in adware, other PUP, or even malware installation (the latter is particularly relevant for sites that host pirated software).

Security experts from lesvirus.fr[4] advise users to be vigilant and spot unfair marketing practices:

  • If the app is available on official stores, always opt for it instead of third-parties' hosted version;
  • Check if Terms and Conditions, Privacy Policy and other relevant documents are provided;
  • Before installing the application, make sure it is not deceptive – check out the comments or reviews online;
  • During the installation, watch out for pre-ticked boxes, file print text, misleading button placements, etc.
  • When prompted, always select Advanced or Custom installation settings and get rid of optional programs.

How to prevent from getting browser hijacker

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
