Test-iq.xyz Virus


If your computer has been infected by Test-iq.xyz, then you have landed yourself what is known as a browser hijackers. Hijackers like Test-iq.xyz can embed themselves in all the most common web browsers, including Chrome, Firefox and others.

Test Iq.xyz

The reason they do this is because they need a browser “host” in order to facilitate their advertising practices. Browser hijackers are, in essence, ad-generating tools that serve the online marketing industry. They usually operate on the basis of popular business models such as Pay Per Click. So in other words, their developers profit every time any of the hijacker-generated ads are clicked on by users such as yourself.

This is a fairly lucrative remuneration system, but it tends to entail a number of other practices that are generally frowned upon by end users and security specialists alike.

For instance, a program like Test-iq.xyz or Hostingcloud.racing is likely to start tracking your browsing patterns in order to tailor its ads to your latest activity. And yes, pretty much everyone does this nowadays. The only difference is that you’re usually asked for permission to have your browsing data collected, whereas with browser hijackers that permission is obtained in a very underhanded way.

The same is also true for the installation tactics that software of this type tends to employ. Do you recall willingly installing Test-iq.xyz on your machine? No?

Then that’s because this piece of software was most probably packaged in the setup of some other free program like a game or some system optimization tool. This distribution method is known as software bundling. And basically it means that when you install the main program in the bundle, you are also installing one or more additional components, such as Test-iq.xyz in this case.

And as a result, you one day open your browser to find it flooded with banners, popups, page redirects and whatnot. Not to mention the obnoxious changes to the browser’s homepage and its default search engine that usually also accompany the presence of such software pieces.

Most times there is a workaround, though. Namely, if you select the custom installation menu, which usually gives you more room to adjust the settings, you should be able to exclude and added components from the installation process. So do keep that in mind the next time you are installing any software on your PC.

But better yet, try to be a little more mindful about the download sources you use, as well. This can potentially save you a great deal of trouble later on along the line. Using sketchy download sources like illegal sites, torrents, etc. comes with the risk of encountering viruses. And the effects of an app like Test-iq.xyz genuinely pale in comparison with the type of consequences that can follow an attack of something like ransomware, Trojan horse viruses and similar threats.

With that in mind, it’s a good idea to also remove hijackers like Test-iq.xyz from your machine, too. Although not malicious in and of themselves, they can expose you to unsafe content in the long run.

So without further ado, below is a detailed removal guide that you can use to rid yourself of Test-iq.xyz and its annoying ads.
