MixBuilder “Virus” – What is It All About?

MixBuilder is a type of program that is spread via shady techniques like freeware installers, software bundles, malvertising, and other undesired apps. It is most likely that its presence on your Mac is a result of its unattended installation. Usually unattended installations of undesired apps happen during the installation of desired programs. There is a way to prevent this annoying side effect – you just need to read carefully all details mentioned in the installers of all newly downloaded apps, especially when they are free. The most important advice we could give you is to select the Advanced/Custom configuration option whenever you see it available in the installer. By doing this you could reveal the presence of bundled apps and eventually opt out their installation.

By being an undesired program or also called potentially unwanted program (PUP), MixBuilder aims to access and alter certain browser settings that will enable it to hijack targeted web browsers. Once the PUP realizes the changes, it obtains the rights to spy on your online behavior which in turn helps it to deliver selected sponsored content right in the affected browser. As a result, all websites you visit are inundated with various deceptive offers. You could see lots of annoying coupons, banners, pop-ups, redirects and pop-unders while browsing the web. Be advised to avoid clicking on the ads you see, as they could land you on bogus websites that present

phishing web pages with fake offers or web pages corrupted by hackers.

According to the information presented on this window, MixBuilder is an app that once installed obtains the permission to:

  • MixBuilder can read sensitive information from webpages, including passwords, phone numbers and credit cards on: all webpages
  • MixBuilder can see when you visit all webpages

Terribly bad news, right?

But is MixBuilder a virus? The answer here is rather ambiguous. On one hand, this program is classified as an undesired program due to the fact that it uses the shady techniques mentioned above to affect users’ devices. As mentioned above, the main issues caused by this program are not related to system and data corruption as is the case with a ransomware infection.

On the other hand, the presence of MixBuilder on your Mac could be used as a security hole by skillful hackers. Since its code is publicly available, hackers could easily obtain and analyze it. Product of their analysis could be the release of a malicious software that exploits some of the identified vulnerabilities. At worst, such a software could enable them to infect your Mac with severe malware threats like Trojan horses.

Considering all issues caused by MixBuilder PUP, we recommend that you should remove it from your Mac as soon as possible.
