How to remove FunctionLogInput browser hijacker from Mac?

What is FunctionLogInput?

FunctionLogInput is a piece of rogue software categorized as a browser hijacker. It operates by promoting (causing redirects to) the search.imah5hf.com fake search engine - through modifications to browser settings. FunctionLogInput also adds the "Managed by your organization" feature to Google Chrome browsers. Software within this category typically has data tracking abilities, which are used to spy on users' browsing activity. Due to the dubious techniques used to proliferate browser hijackers, they are classified as PUAs (Potentially Unwanted Applications) as well.

FunctionLogInput browser hijacker installed onto Google Chrome

Browser hijackers primarily target popular browsers with large user bases. This software reassigns browsers' homepage, default search engine, and new tab/window URLs - to the addresses of fake web searchers. FunctionLogInput also makes these alterations to browser settings when promoting search.imah5hf.com. Hence, with this browser hijacker installed: new browser tabs/windows opened and search queries typed into the URL bar - redirect to the search.imah5hf.com web searcher. Illegitimate search engines are seldom able to provide search results, so they tend to redirect (or cause redirection chains leading) to Google, Yahoo, Bing, and other genuine ones. This applies to search.imah5hf.com as well; it redirects to the Google (google.com) search engine.

Furthermore, browser hijackers can reset any changes users try to make to their browsers and/or restrict/deny access to the browser settings outright. Therefore, recovering a hijacked browser is impossible without removing the software affecting it. What is more, most browser hijackers can track data, which is likely to be the case with FunctionLogInput. Targeted information includes (but is not limited to): URLs visited, webpages viewed, search queries typed, IP addresses, geolocations, and personally identifiable details. The collected 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 result in severe privacy issues, financial losses, and even identity theft. Therefore, to ensure device integrity and user safety, it is crucial to remove all suspect applications and browser extensions/plug-ins immediately upon detection.

UltraWebFormatFire SearchSearch Lime, and OriginalSearchManager are a few examples of browser hijackers. They appear legitimate and offer various "handy" functionalities. However, the advertised functions are usually nonoperational. In fact, this is true of practically all PUAs. The sole purpose of unwanted apps is to generate profit for the developers; they have no real value to users. Instead of delivering on any promises, PUAs can hijack browsers, cause redirects, run intrusive advertisement campaigns (adware), and gather vulnerable and private information.

How did FunctionLogInput install on my computer?

PUAs are distributed through download/installation setups of other programs. This deceptive marketing method of packing regular software with unwanted or malicious additions - is named "bundling". Rushed download/installation processes (e.g., ignored terms, skipped steps and sections, etc.) increase the risk of inadvertently allowing bundled content into the system. Intrusive adverts are used to proliferate PUAs as well. Once clicked on, the ads can execute scripts to download/install these applications without user consent. Some PUAs also have "official" promotional/download webpages.

How to avoid installation of potentially unwanted applications?

It is recommended to research software before download/installation and/or purchase. Additionally, only official and verified download channels must be used. Untrustworthy sources, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - commonly offer harmful and bundled content. When downloading/installing, it is important to read terms, study all possible options, use the "Custom/Advanced" settings, and opt-out from additional apps, tools, features, etc. Intrusive advertisements appear ordinary and innocuous; however, they redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, and so on). In case of encounters with ads and/or redirects of this kind, the system must be inspected and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
