How to uninstall UnitHandler adware
Written by Tomas Meskauskas on (updated)
What is UnitHandler?
UnitHandler displays advertisements and modifies browser settings to promote a specific address. In this way, it functions as adware and as a browser hijacker.
Typically, users do not download or install apps like UnitHandler intentionally and, therefore, this application falls into the category of potentially unwanted applications (PUAs).
UnitHandler is distributed via deceptive installer, which emulates the Adobe Flash Player installer.
UnitHandler serves pop-ups, banners, coupons, surveys, and other advertisements. Commonly, ads displayed by adware are used for advertising untrusted pages (e.g., download pages for various PUAs, scam websites). Sometimes they are used to distribute unwanted software: once clicked, they execute scripts that download and even install unwanted apps. These ads conceal underlying content of visited pages and/or the user interface.
Furthermore, UnitHandler changes browser settings. Typically, apps of this type hijack browsers by altering the address of the homepage, new tab and homepage, assigning them to the address of a fake search engine. Fake search engines generate misleading results, display ads, and show search results generated by legitimate search engines.
Browser hijackers (including UnitHandler) often prevent modification of settings. Therefore, browser can be stopped from opening a specific address only by uninstalling the hijacker from the browser and operating system.
UnitHandler might also gather various information. These apps target addresses of visited pages, entered search queries, IP addresses, geolocations, and other information relating to internet browsing habits. Some adware-type apps can read can read sensitive information from websites such as passwords, telephone numbers, and credit card details. This might also be the case with UnitHandler. Apps that gather personal information should never be installed, since developers can sell gathered details to third parties (potentially cyber criminals) or monetize them in other ways. Depending on the obtained data, it could be misused for various malicious purposes, for example, to make fraudulent purchases and transactions, and to steal personal accounts, identities.

Never trust adware or have it installed. As mentioned, most users download and install adware/browser hijackers and other PUAs inadvertently.
How did UnitHandler install on my computer?
UnitHandler is distributed through a fake installer that is designed to appear like a legitimate installer for Adobe Flash Player. Fake, third-party installers are used to distribute malicious programs such as Trojans and ransomware.
Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software. This distribution method is known as "bundling".
Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default.
In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.
How to avoid installation of potentially unwanted applications
You are advised to download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.
Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations.
Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from the operating system.
If your computer is already infected with UnitHandler, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
