How to remove the UltraWebFormat browser hijacker?
Written by Tomas Meskauskas on (updated)
What is UltraWebFormat?
UltraWebFormat is a piece of rogue software categorized as a browser hijacker. It operates by promoting (causing redirects to) the search.7ax6.com fake search engine - by making changes to browser settings.
Additionally, UltraWebFormat adds the "Managed by your organization" feature to Google Chrome browsers. Typically, software within this category also has data tracking abilities, which are employed to spy on users' browsing habits.
UltraWebFormat likely has such functionalities as well. Since most users download/install browser hijackers inadvertently, they are classified as PUAs (Potentially Unwanted Applications) as well.
Browser hijackers mainly target popular browsers like Google Chrome, Safari, Mozilla Firefox, and so on. Following successful infiltration, this software assigns fake web searcher addresses as browsers' default search engine, new tab/window, and homepage URLs.
To elaborate on how these alterations affect browsing, with UltraWebFormat installed: new browser tabs/windows opened and search queries typed into the URL bar - redirect to the search.7ax6.com search engine. Illegitimate web searchers are usually unable to provide search results, so they redirect (or cause redirection chains leading) to legitimate search engines.
This applies to search.7ax6.com as well; it redirects to the Google (google.com) search engine. Furthermore, browser hijackers can limit/deny access to the browser settings and/or undo any permitted changes made.
Therefore, restoring an affected browser is impossible without removing the software hijacking it. What is more, most browser hijackers can track data.
Targeted information includes: URLs visited, pages viewed, search queries typed, IP (Internet Protocol) addresses, geolocations, personally identifiable and other vulnerable details. The gathered data is then monetized by being shared with and/or sold to third-parties (potentially, cyber criminals).
To summarize, the presence of data-tracking software on browsers/systems - can lead to severe privacy issues, financial losses, and even identity theft. Therefore, it is strongly advised to immediately remove all suspect applications and browser extensions/plug-ins.

Fire Search, Brilliant Check, OriginalSearchManager, and MovieFinder365 are a few examples of browsers hijackers. They typically appear legitimate and useful.
However, their features rarely work as advertised, and in most cases - they do not work at all. This is true of practically all PUAs. The sole goal of unwanted software is to generate revenue at user expense.
Therefore, instead of delivering on any promises, PUAs can cause redirects, hijack browsers, run intrusive advertisement campaigns (adware), and gather private information.
How did UltraWebFormat install on my computer?
PUAs can be downloaded/installed alongside other software. This false marketing method of packing regular programs with unwanted or malicious additions - is termed "bundling".
By rushing through download/installation processes (e.g., skipping steps and sections, using pre-set options, etc.) - users risk unintentionally allowing bundled content into their devices. Intrusive advertisements are also used to proliferate PUAs.
Upon being clicked, intrusive ads can execute scripts to download/install these applications without user permission. PUAs may have "official" promotional/download webpages as well.
How to avoid installation of potentially unwanted applications?
It is highly recommended to research software products before download/installation and/or purchase. Additionally, all downloads must be performed from official and verified sources. Untrustworthy download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks (Torrent clients, eMule, Gnutella, etc.), and other third-party downloaders - often offer dangerous and/or bundled content.
When downloading/installing, it is important to read terms, explore possible options, use the "Custom/Advanced" settings, and opt-out from supplementary apps, tools, functions, etc. Intrusive adverts appear ordinary and harmless; however, they redirect to unreliable and questionable sites (e.g., gambling, pornography, adult-dating, and so on).
Should users experience such ads and/or redirects, they must inspect their devices and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
