MixBuilder Virus (Mac)

Also Known As: MixBuilder adware
Type: Mac Virus
Damage level: Medium

What is MixBuilder?

MixBuilder is a potentially unwanted app (PUA) classified as adware. If this app is installed, it indicates that there are more adware-type apps already installed on the system. MixBuilder app is installed through other ad-supportive software without users' consent.

Users with apps of this type installed on their systems are continually served with unwanted ads. Furthermore, PUAs often gather information relating to users' browsing habits.

MixBuilder adware

When installed, these PUAs deploy intrusive ads, such as pop-up ads, coupons, banners, surveys, etc. Generally, they are displayed using tools that enable placement of third party graphical content on any site. Therefore, ads displayed by adware conceal underlying content of visited websites.

This can be very frustrating. When clicked, they cause unwanted redirects, opening untrustworthy websites that often contain/promote malicious software. Clicking these ads often allows them to run scripts designed to download and install various PUAs.

Furthermore, these PUAs usually record user-system information relating to browsing activity such as IP addresses, geolocations, URLs of visited websites, entered search queries, and other data. These apps sometimes target personal, sensitive details. Developers share the information with third parties who misuse it to generate revenue.

Some of these third parties might be cyber criminals. If you discover aware-type (or other) PUAs installed, remove them immediately, since they can lead to problems with browsing safety, online privacy, and even identity theft.

ChangeToPDF, PDF Mac Master, and Snap Media Player are just some examples of other adware-type apps that operate in a similar way to MixBuilder. Developers present these apps as useful tools that supposedly provide various features and other benefits.

In fact, they cause unwanted redirects, display ads, and gather data. They are used to generate revenue for their developers and deliver none of the promoted functions.

How did MixBuilder install on my computer?

In this particular case, MixBuilder is installed through other adware. Typically, rogue software is installed through another package when developers use the "bundling" method. They include (bundle) unwanted apps into software set-ups, hiding them in settings such as "Custom", "Advanced", and other similar parts.

Furthermore, many people download and install software without checking settings, thereby causing unwanted installations. Clicking intrusive ads capable of executing scripts also cause unwanted downloads and installations.

How to avoid installation of potentially unwanted applications?

Browse the web and download all software with care. Download using official and trustworthy websites, and not third party downloaders, unofficial websites, torrent clients, eMule or other Peer-to-Peer networks. Check "Custom", "Advanced" and other settings when downloading and installing software, especially if it is free software.

Ensure that you opt-out of offers to install potentially unwanted applications. Furthermore, avoid clicking ads displayed on dubious web pages, since they might open other sites relating to gambling, adult dating, pornography, and so on. If these redirects happen without clicking any ads, or unwanted ads appear on all pages, this might be due to installed PUAs.

Check the list of installed browser extensions, plug-ins and add-ons, and remove all suspicious/unwanted entries immediately. The same applies to unwanted programs installed on the computer/operating system. If your computer is already infected with MixBuilder, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
