Qubiv is the name of a website that allows users to play Flash-based online games free of charge. The website also offers its users the opportunity to download the Qubiv Web browser extension, which may introduce a toolbar to Web browsers like Chrome, Firefox and Internet Explorer. The Qubiv toolbar provides a search field, as well as quick links to some of the most popular games on Qubiv. Keep in mind that every ‘feature’ that Qubiv offers can be accessed by visiting Qubiv’s official website easily, and this does not require the installation of 3rd-party software.
Qubiv is identified as a Potentially Unwanted Program, which means that this extension isn’t unsafe necessarily but it may be characterized by poorly implemented features or dubious behavior. According to the terms of service published on Qubiv’s website, the browser extension is also ad-supported. This means that users who have activated the Qubiv extension may be exposed to 3rd-party marketing content while they browse some of their favorite websites. ‘Qubiv Ads’ may sometimes be used to promote other Potentially Unwanted Programs, as well as low-quality websites, so it is recommended to avoid visiting any of the URLs they promote.
Since Qubiv’s ‘features’ can be accessed by simply visiting the official website, there’s no reason for you to install the dubious extension they offer. If you already have the Qubiv PUP installed and wish to remove it, you should check your list of installed browser extensions and remove it from there.
