How to remove FlexibleProtocol adware from your operating system

What is FlexibleProtocol?

FlexibleProtocol is an adware-type application with browser hijacker characteristics. It operates by delivering intrusive advertisement campaigns and making changes to browser settings to promote fake search engines. In addition, this app has data tracking capabilities, which are used to collect browsing-related information.

Due to the dubious techniques employed in FlexibleProtocol's distribution, it is also classified as a Potentially Unwanted Application (PUA).

Adware enables the placement of various banners, pop-ups, banners, coupons and other intrusive advertisements, typically on any visited website. The delivered ads overlay web page content and reduce browsing speed, thereby significantly diminishing the browsing experience. Furthermore, when clicked intrusive ads can redirect to untrusted, misleading, compromised and malicious websites. Some of the advertisements can even be triggered (when clicked) to stealthily download/install software (e.g. PUAs).

Browser hijackers assign the addresses of fake search engines as the homepage, default search engine and new tab/window URLs. Therefore, with this software installed, each new browser tab/window opened and search made via the URL bar redirects to the promoted address.

Bogus search engines are seldom able to provide search results, and so they tend to redirect to Google, Bing, Yahoo and other genuine sites. Browser hijackers can undo any changes users attempt to make to their browsers and/or limit/deny access to the browser settings outright. Therefore, recovering a hijacked browser is impossible without removing the software affecting it.

Furthermore, most PUAs (adware and browser hijackers included) can track data. They can 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 gathered data usually contains personally identifiable information. PUA developers monetize such data by sharing it with and/or selling it to third parties (potentially, cyber criminals).

In summary, the presence of these unwanted apps on devices can result in system infections, financial loss, serious privacy issues and even identity theft. To ensure device and user safety, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

SmartSearch, MicroLookup, SmartControl and AdminLink are some examples of other applications within the adware classification. They may seem legitimate and offer various "useful" functionality, however, the advertised features are rarely operational.

In fact, this is true of most PUAs. The only purpose of this unwanted software is to generate revenue for the developers. Rather than delivering any real value, PUAs run intrusive ad campaigns, cause redirects, hijack browsers and collect private data.

How did FlexibleProtocol install on my computer?

PUAs are distributed via download/installation set-ups of other products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling".

Rushing download/installation processes (e.g. ignoring terms, skipping steps and settings, etc.) increases the risk of inadvertently allowing bundled content into the system.

Some PUAs have "official" download sites. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications?

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.

When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on.

Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others). If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately.

Installed programs must be activated and updated with tools or implemented functions that are provided by the official developers. No other third party, unofficial tools should be used.

Note that it is illegal to activate licensed software with ‘cracking’ tools. Files and programs should be downloaded from official websites and via direct download links. Avoid third party installers and the tools/sources mentioned above.

Do not open website links or files in irrelevant emails that are received from unknown, suspicious addresses. These bogus emails are often disguised as official and important. Regularly, scan your computer with reputable, up-to-date antivirus or anti-spyware software.

If your computer is already infected with FlexibleProtocol, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
