Chromium Shield browser removal instructions
What is Chromium Shield?
Chromium Shield is a rogue browser, based on a legitimate, open-source project called Chromium. This piece of software is endorsed as supposedly capable of providing safe, secure and fast browsing. Amongst its listed features are: free VPN; advertisement blocking; protection against tracking, surveillance and censorship; increased widow/tab response (i.e. decreased "freezing" of windows), and so on. However, the Chromium Shield browser operates as adware (i.e. delivers intrusive advertisement campaigns) and promotes fake search engines (e.g. opti-page.com). Due to the questionable techniques used to distribute Chromium Shield, it is also deemed to be a PUA (Potentially Unwanted Application). Additionally, most PUAs spy on users' browsing activity and collect sensitive information extracted from it. Hence, it is highly likely that Chromium Shield has such data tracking abilities as well.
Rogue adware-type browsers create a "virtual layer", which enables them to place intrusive advertisements (e.g. pop-ups, banners, coupons, surveys, full-page and other ads) - on any visited webpage. Hence, the adverts do not originate from the websites themselves. These advertisements seriously diminish the browsing experience, as they overlay page content and slow down the browsing speed. Furthermore, once clicked on, intrusive ads redirect to various untrustworthy/malicious sites and some can even stealthily download/install software (e.g. PUAs). Through these websites and/or installed software - users can experience a wide variety of severe problems. As mentioned in the introduction, Chromium Shield also promotes opti-page.com - an illegitimate search engine. It does so, by redirecting to this web searcher (opti-page.com) every time a new browser tab/window is opened and/or web search is done via the URL bar. Fake search engines are rarely able to provide search results, so they tend to redirect to Google, Yahoo, Bing and other legitimate ones. Even if illegitimate web searchers can generate search results, they are typically inaccurate and/or promote unreliable and dangerous webpages. Furthermore, most PUAs can track data. They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). This vulnerable data is then shared with and/or sold to third parties (potentially, cyber criminals), likewise intent on misusing it for profit. In summary, presence of unwanted software on devices can result in system infections, serious privacy issues, financial losses and even identity theft. To protect device and user safety, all suspicious applications and browser extensions/plug-ins must be eliminated without delay.

WebNavigatorBrowser, Email Assistant, Citrio, TappyTop and WebExplorer are some examples of other Chromium-based dubious browsers. They appear legitimate and offer a wide variety of "useful" and "advantageous" functionalities. However, these functions seldom work as advertised and in most cases - they do not work at all. In fact, this applies to practically all PUAs. Functionality and user safety are irrelevant, since the only purpose of unwanted apps is to generate revenue for the developers. Therefore, instead of delivering on any promises, PUAs can run intrusive advert campaigns, force-open unreliable and malicious webpages, modify browsers (browser hijackers), gather vulnerable and personally identifiable information.
How did potentially unwanted applications install on my computer?
Some PUAs (e.g. Chromium Shield) have "official" promotional pages, from which they can be downloaded. These apps can also be downloaded/installed together with other programs. This deceptive marketing method of pre-packing regular software with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g. ignored terms, skipped steps, used "Easy/Express" settings, etc.) increase the risk of inadvertently allowing bundled content into the system. Intrusive adverts proliferate PUAs as well. Upon being clicked, the ads can execute scripts to download/install such applications without user permission.
How to avoid installation of potentially unwanted applications?
It is recommended to research software products to verify their legitimacy, prior to download/installation and/or purchase. All downloads must be done from official and trustworthy sources. Since dubious download channels, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - often offer harmful and/or bundled content. When downloading/installing, it is important to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features and other additions. Intrusive advertisements appear legitimate, however they redirect to highly questionable sites (e.g. gambling, pornography, adult-dating, etc.). In case of encounters with ads and/or redirects of this kind, the system must be inspected and all suspect applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
