What is WebExplorer Browser?

WebExplorer Browser is a rogue Chromium-based browser, which supposedly simplifies the browsing experience. In fact, this software functions as adware (it is designed to serve various advertisements) and promotes onesearch.org, the address of a fake search engine. It is also likely to collect browsing-related information. In any case, do not trust, download, or install the WebExplorer Browser or other dubious browsers.

WebExplorer Browser pop-up redirects

Typically, adware-type applications feed users with coupons, banners, surveys, pop-ups and other advertisements that tend to promote dubious websites. These ads might be designed to execute scripts to download and install potentially unwanted applications (PUAs). Therefore, you are advised against trusting or clicking ads that appear due to installed adware (in this case, the rogue WebExplorer Browser). Furthermore, this browser promotes a fake search engine (onesearch.org), which is assigned as WebExplorer's default search engine. Research shows that onesearch.org displays results generated by Yahoo - when used, it simply redirects to search.yahoo.com. Therefore, onesearch.org is a useless search engine. Note that fake search engines promote dubious websites by including them into a list of generated results. As mentioned, WebExplorer Browser might be designed to help the developers to generate revenue by collecting data. Typically, programs of this type target details relating to users' browsing habits such as, for example, IP addresses, geolocations, addresses of visited pages, and entered search queries. In some cases, these apps collect private, sensitive information as well. Developers generate revenue by selling the details to third parties (potentially, cyber criminals), or by misusing them in other ways. To avoid problems relating to browsing safety and online privacy, becoming a victim of identity theft, causing unwanted downloads and installations, remove the WebExplorer Browser from your computer.

More examples of dubious browsers are Citrio, Secure Browser and WebShield. These browsers tend to promote other rogue addresses (e.g., fake search engines), serve ads, and collect data. Commonly, developers advertise them as useful and legitimate, but they deliver no real value and can cause serious problems.

How did adware install on my computer?

In some cases, people download and install potentially unwanted apps (PUAs) intentionally, since they are advertised as useful, legitimate applications. Users also download and them inadvertently when they are included as 'additional offers' within the set-ups of other software. This distribution method is known as "bundling". In most cases, offers to download and install PUAs are mentioned in (and can be declined through) settings such as "Advanced", "Custom", "Manual" and others. Many users fail to check these settings when they download and install their software, thereby allowing PUAs to infiltrate. Sometimes unwanted downloads/installations happen when people click deceptive ads that run certain scripts.

How to avoid installation of potentially unwanted applications

Programs and files should never be downloaded or installed through third party downloaders/installers. It is not safe to use unofficial websites, Peer-to-Peer networks (torrent clients, eMule) or other channels of this kind to download your software. Use official websites and direct links. Check all settings such as "Custom" and "Advanced" and decline offers to download or install additional software before finishing the process. Do not click intrusive ads that appear on dubious websites, since they can open untrusted websites or cause download/installation of unwanted, potentially malicious applications. Remove any suspicious, unwanted extensions, add-ons and plug-ins already installed on the browser immediately. The same should be applied to programs of this kind that are installed on the operating system. If your computer is already infected with rogue applications, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
