How to remove the ConvertrzSearch browser hijacker

What is ConvertrzSearch browser hijacker?

ConvertrzSearch is a browser hijacker designed to modify browser settings to promote a fake search engine (ConvertrzSearch promotes convertrz-search.com in this manner). Additionally, this browser hijacker has data tracking capabilities, which are used to monitor browsing activity.

Due to the dubious methods employed to proliferate ConvertrzSearch, it is classified as a Potentially Unwanted Application (PUA).

Google Chrome, Mozilla Firefox, Internet Explorer and other popular browsers are common targets of browser hijackers. They operate by assigning the addresses of fake search engines as the homepage, default search engine and new tab/window URLs. Therefore, each search query typed into the URL bar and new browser tab/window opened redirects to the promoted address.

ConvertrzSearch promotes convertrz-search.com in this manner as well. Rogue search engines are seldom capable of providing unique results, and so they redirect to (or cause redirection chains ending with) Google, Yahoo, Bing and other genuine sites. This is also the case with convertrz-search.com, which redirects to Yahoo (search.yahoo.com).

 Furthermore, recovering a hijacked browser is impossible without removing the software affecting it, since browser hijackers can restrict/deny access to the browser settings and/or undo any permitted changes made. As mentioned, ConvertrzSearch can track data.

It can record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). The collected data typically contains personally identifiable information.

The developers monetize this information by sharing it with and/or selling it to third parties (potentially, cyber criminals). Therefore, the presence of data-tracking content on browsers/systems can lead to financial loss, serious privacy issues and even identity theft.

To ensure device integrity and user safety, you are strongly advised to eliminate all suspect applications and browser extensions/plug-ins immediately upon detection.

RadioSearches, SearchPDFConverterHD, and Nebula Search are some examples of browser hijackers. They may seem normal and offer various "useful" functionality, however, despite how good the features promised may sound, they are usually nonoperational. In fact, this applies to most PUAs.

The only purpose of this unwanted software is to generate revenue for the developers. Rather than delivering any real value, PUAs hijack browsers, force-open untrusted and malicious web pages, run intrusive advertisement campaigns and gather private data.

How did ConvertrzSearch install on my computer?

Some PUAs (including ConvertrzSearch) have "official" promotional sites, from which they can be downloaded. These apps are also distributed via download/installation set-ups of other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".

Rushing download/installation processes (e.g. ignoring terms, skipping steps, using pre-set options, etc.) increases the risk of unintentionally allowing bundled content into the system. Intrusive ads proliferate such applications as well. Once clicked, they can execute scripts to stealthily download/install PUAs.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation and/or purchase. All downloads must be done from official and verified sources. Untrusted channels such as unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders commonly offer deceptive and/or bundled content.

When downloading/installing, read the terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements may seem legitimate and harmless, however, they can redirect to dubious sites (e.g. gambling, pornography, adult-dating, etc.).

If you encounter ads/redirects of this type, inspect your device and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with ConvertrzSearch, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
