How to remove PremierOpinion from computers
Written by Tomas Meskauskas on (updated)
What is PremierOpinion?
Created by VoiceFive Inc, the PremierOpinion program claims to help users to express their opinions about products and services that matter most to them. By participating in online research, PremierOpinion members have the opportunity to influence leading companies while earning cash rewards, gift cards, or entries into valuable sweepstakes.
While this functionality may seem legitimate, be aware that the PremierOpinion app is categorized as adware or an unwanted application since it displays surveys on various shopping websites.
Many users report that this browser plug-in was installed on their Internet browsers (Internet Explorer, Google Chrome, and Mozilla Firefox) without their consent, and furthermore, many experience diminished browser performance as a result. The developers of the PremierOpinion app employ a deceptive software marketing method called 'bundling' for distribution.
More about PremierOpinion
Unwilling installation of this adware is often a consequence of not paying close enough attention when downloading and installing free software. Be aware that many download websites and freeware developers bundle their free downloads and programs with additional promoted software such as toolbars, browser add-ons, etc to monetize incoming web traffic.
If you do not pay close attention by checking each step during the freeware installation phase, you may inadvertently install PremierOpinionor or other adware. This plug-in is not technically a computer virus, however, it is categorized as adware and you are advised to remove it from your computer since it tracks users' Internet browsing activity.
After successful installation, PremierOpinion tracks IP addresses, websites visited (and interactions with those sites), Internet search terms, videos viewed, products purchased from online shops, form data, content downloaded or uploaded, and other software and hardware information that can be personally identifiable. This tracking can result in privacy issues and identity theft.

How did adware install on my computer?
Most adware is distributed via small programs called 'download managers' within freeware download websites such as download.com, soft32.com, softonic.com, amongst many others. PremierOpinion adware is similar to other unwanted programs that are distributed via free software downloads.
Examples include Consumer Input, PicRec, Easy Deals, and SelectNGo. Most freeware download websites employ download managers to monetize their free services by offering installation of promoted browser extensions together with the chosen free software.
Thus, careless download and installation of free software may lead to adware or malware infections. This situation can be prevented by closely inspecting each step of the freeware download process and never accepting installation of any additional applications offered.
If you are installing downloaded software, select the 'Custom' or 'Advanced' installation options, rather than 'Typical' or 'Quick' - this will reveal any bundled applications listed for installation and enable you to decline them. Computer users who have installed PremierOpinion should follow this removal guide to eliminate this adware from their Internet browsers.
