WebFox browser removal instructions

What is WebFox?

WebFox is a rogue browser, based on an open-source project called Chromium. It is endorsed as a browser that offers faster and safer browsing. In addition, it has a feature that allows users to access certain browser functions straight from the desktop. However, WebFox is classified as adware. It runs intrusive advertisement campaigns, i.e. delivers various misleading, deceptive and possibly malicious ads. Due to the dubious methods used to distribute WebFox, it is also considered to be a PUA (Potentially Unwanted Application). Furthermore, most PUAs have data tracking abilities, which are employed to spy on users' browsing activity.

Adware-type browsers create a "virtual layer" that enables the place of third party graphical content on any visited website. This adware delivered material includes: pop-ups, banners, surveys, coupons, full-page and other intrusive advertisements. The adverts do not originate from the sites themselves and seriously diminish the browsing experience. Intrusive ads limit webpage visibility and browsing speed. However, these advertisements are more than just a nuisance, they also pose a threat to device/user safety. Once clicked on, intrusive adverts redirect to a variety of untrustworthy and malicious websites. What is more, some of the ads can be triggered (by being clicked on) to execute scripts, designed to stealthily download/install software. PUAs are a prime example of content infiltrated into systems in this manner. Unwanted apps can have different heinous functions and these functionalities can be in varied combinations; e.g. they can deliver intrusive advert campaigns, cause redirects and/or hijack browsers. As mentioned in the introduction, most PUAs can track data. They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect sensitive information extracted from it (IP addresses, geolocations and other details). The collected data is likely to include personally identifiable information and PUA developers monetize it by sharing/selling the data to third parties (potentially, cyber criminals). In summary, presence of unwanted software on devices can result in system infections, severe privacy issues, financial losses and even identity theft. To ensure device integrity and user privacy, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

Chromium ShieldWebExplorer BrowserEmail AssistantWebShield and TappyTop are some examples of other rogue Chromium-based browsers. They appear legitimate and typically offer a broad range of "useful" features. However, despite how good the advertised functionalities may sound - they are rarely operational. In fact, this is true of practically all PUAs. The only goal of this software is to generate profit for the developers; therefore, functionality and user safety are irrelevant. PUAs are designed to run intrusive advertisement campaigns, force-open untrustworthy and malicious webpages, hijack browsers and collect private data.

How did potentially unwanted applications install on my computer?

Some PUAs (e.g. WebFox) have "official" promotional sites, from which they can be dowloaded. These applications can also be downloaded/installed together with other programs. This false marketing technique of packing ordinary products with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g. ignored terms, skipped steps, used pre-set options, etc.) increase the risk of inadvertently allowing bundled content into the system. Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to download/install this software without user permission.

How to avoid installation of potentially unwanted applications?

It is recommended to research products before download/installation and/or purchase. All downloads must be done from official and verified sources. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - are deemed to be untrustworthy, due to commonly offering harmful and/or bundled content. When downloading/installing, it is important to read terms, study all available options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features and other additions. Intrusive adverts appear legitimate, however they redirect to unreliable and questionable webpages (e.g. gambling, adult-dating, pornography, etc.). In case of encounters with ads and/or redirects of this type, the system must be inspected and all suspicious applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
