About Duoso.com

Duoso.com is a browser hijacker, sometimes referred to as a redirect virus due to its annoying habit of redirecting users. It is not a malware infection and not really a serious one so you should not be too concerned if you find it on your computer. It probably entered your computer when you were installing freeware.


Hijackers are oftentimes added to freeware as additional offers and if you do not notice them during installation, they will be allowed to install alongside. And you will not know until it has already hijacked your browser. It will take over your browser, change settings so that Duoso.com is set as your homepage and new tabs. It may then try to redirect you to sponsored pages so that it could generate income. It will not help you in any way, so there’s no use in keeping the hijacker. Delete Duoso.com.

Why uninstall Duoso.com?

The most obvious sign of a hijacker infection is the change to your browser’s settings. Duoso.com will, without your permission, set itself as your homepage and new tabs and that means that it will load every time you open your Internet Explorer, Google Chrome and Mozilla Firefox browsers. These changes are irreversible unless you first remove Duoso.com from the computer. The homepage change is very obvious since the site is in Chinese, and if you do not speak the language, you will be very lost. There will be links provided on the site as well as a search engine, all of which we do not suggest you use. The site does not look safe, especially because it used such a sneaky method to infiltrate. If you use the search engine, you will be taken to Baidu.com and you might encounter plenty of sponsored websites inserted among the legitimate results. A lot of hijackers do this because that is how they earn income. One of the biggest reasons why you should delete Duoso.com right away is the possibility of it being able to lead you to malicious content.

It is not difficult to prevent the installation of hijackers, adware and other kinds of unwanted programs. Since they are attached to freeware, you need to stay vigilant when installing them. Use Advanced or Custom settings because that is where extra offers will be hiding. If there is something, just uncheck the boxes and you can continue installing the freeware. Unless you want to regularly have to uninstall Duoso.com or similar, refrain from using Default settings and instead, choose Advanced.
