PremierOpinion Unwanted Application (Mac)

What is PremierOpinion?

According to the developers, the PremierOpinion app monitors browsing activity. In exchange for allowing PremierOpinion to perform this function, users are supposedly rewarded with access to certain software, entries to "sweepstakes", and other benefits.

In fact, developers proliferate PremierOpinion using the "bundling" method and thus it often infiltrates systems without permission. PremierOpinion is categorized as a potentially unwanted application (PUA).

As mentioned above, PremierOpinion is designed to track information. The list of collected data types usually includes system information and web browsing activity (IP addresses, websites visited, pages viewed, and so on). This application also periodically delivers pop-up windows and surveys that users must complete.

In this way, PremierOpinion collects additional information such as users' names, ethnicity, native languages, email addresses, and so on. It is stated that the information is used to help the "industry" understand digital content trends and patterns, however, there is a high probability that collected data will be used for other dubious purposes.

Although it is not yet confirmed, there is a chance that developers will sell data to third parties (potentially, cyber criminals) who might attempt to misuse private information to generate revenue. Therefore, the presence of a data-tracking app can lead to serious privacy issues.

We recommend that you consider uninstalling the PremierOpinion application. As mentioned, this app is distributed using the "bundling" method, which is often used to proliferate several potentially unwanted applications (mostly adware and browser hijackers) at once. Therefore, as well as removing PremierOpinion, also remove other dubious applications and browser plug-ins.

There are dozens of potentially unwanted applications online, all of which are virtually identical. By offering "useful features", they attempt to give the impression of legitimacy, however, they often provide no value for regular users (claims to provide these features often false).

These unwanted applications gather information, cause unwanted redirects, and deliver advertisements, thereby posing a direct threat to your privacy and computer safety.

How did potentially unwanted applications install on my computer?

PremierOpinion is free for anyone to download on its official website, however, developers proliferate it using a deceptive marketing method called "bundling" - stealth installation of third party apps with regular software/apps.

Developers are not honest enough to disclose these informations properly and conceal bundled apps within "Custom/Advanced" options or other sections of the download/installation processes. In addition, many users rush these processes and skip steps - behavior that often leads to inadvertent installation of unwanted applications such as PremierOpinion.

How to avoid installation of potentially unwanted applications?

As well as "bundling", potentially unwanted applications are often distributed using intrusive advertisements that redirect to malicious websites and execute scripts that download/install PUAs (or even high-risk malware). To prevent this situation, be very cautious when browsing the Internet and downloading/installing software.

Carefully analyze each step of the download/installation processes, opt-out of additionally-included programs, and decline offers to download/install them. Avoid using third party downloaders/installers, since developers monetize them by promoting ("bundling") software. Apps should be downloaded only from trusted sources, using direct download links.

Bear in mind that developers invest many resources into intrusive ad design, thereby making them seem legitimate. In fact, these ads redirect to dubious websites (pornography, adult dating, etc.). If you experience these redirects, remove all dubious applications and browser plug-ins.

The key to computer safety is caution. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
