adware.WizardUpdate – a Mac virus that hijacks its browsers and shows unwanted advertisements
WizardUpdate adware is an intruder that also has browser hijacker functions. The PUP affects Mac devices by changing certain browser settings, such as the default search engine, new tab, and homepage. It triggers redirects to a fake search engine and other commercial sites. It also displays various advertisements, pop-ups, banners. In most cases it doesn't generate any search results itself, users are more often redirected to a legitimate search in search.yahoo.com and the list gets filled with links and other possibly dangerous material.
If you've identified any of these indications, then the adware is more likely installed on your Mac device. Due to the sneaky techniques used for its distribution and the fact that it can gather various browsing-related data, this software is considered a potentially unwanted program (PUP) besides being a macOS-specific threat. This article explains how this junkware spreads, the threats it poses, how to get rid of it, and maintain excellent system health. There is no need to rely on such programs and browser-based applications.

adware.WizardUpdate derives from the well-known adware family of Adload, which affects mostly Mac devices. There are many variations, from browser hijackers to adware, including OptimalUnit, AuraSearch, and NetInput, to name just a few. They all function slightly differently, but they all pose a threat to the user and impede their overall browsing experiences.
Some of these PUPs are capable of collecting browsing information, such as:
- computer and browser details,
- IP addresses,
- geolocations,
- search queries,
- visited sites,
- and so on.
All this gathered data might be sold to or shared with third-parties with ill intentions. Those redirects that shows and other advertising material that you encounter can lead to tracking and recording of such details too. Data is not identifiable but can lead to privacy issues and exposure to possibly dangerous online content.
Furthermore, all these redirects can show unwanted ads with an inappropriate adult, gambling, or other mischievous content. The shown material can have nothing to do with the websites the user will be redirected to if the ads are clicked. In addition, users might be tricked into downloading additional PUPs.
That's why our cybersecurity team recommends all macOS users to refrain from installing this PUP. If they already have it, then to remove adware from their devices. Anti-malware tools like MalwarebytesMalwarebytes and SpyHunterCombo Cleaner should be used to uninstall this potentially unwanted program.
As great as these tools might be to remove malware and prevent it from entering the computer, it can't do everything. Users will have to finish removal manually. We provide detailed instructions on how to eliminate this browser hijacker from all browsers. You can reset the web browser fully to avoid the tedious job of deleting all applications by hand.
Due to its unpleasant operating features, some people might call this browser intruder a WizardUpdate virus. Whatever you name it, you have to take care of your device's health after getting rid of it. IT specialists[2] suggest using the powerful FortectIntego system repair tool for this task.
Deceptive distribution techniques of potentially unwanted programs
Developers of adware, browser hijackers, and other PUPs have many weapons at their disposal when we're talking about distribution methods. Although our cybersecurity research team has conducted research that revealed that two of the most popular means to spread PUPs are deceptive ads and bundled software. In fact, another research shows[3] that 62% of the top 50 applications on one of the most popular software vendors website contained PUPs.
Deceptive ads might tempt users to install unwanted software by claiming that they have a virus infection, their software is out of date, or any other similar lie. Flash Player updates and other software promotions can lead to PUP infections. This is especially common with macOS intruders. Websites cannot determine if your software is out of date or not, and they surely can't detect any malware that might be infecting your computer. Don't fall for these types of tricks, or you'll have to deal with PUP removal.
Freeware (or software) bundles are another popular way to spread PUPs. With such bundles, two or more apps are offered, and boxes agreeing to install the additional software are preselected. If you desperately want some program from a bundle, then take your time and choose Advanced/Custom installation mode instead of the Standard/Quick/Recommended one, and deselect all pre-ticked boxes from apps you're not willing to install.
