QuickShare - how to eliminate unwanted coupon ads?

What is QuickShare?

The QuickShare browser add-on is developed by Linkury and enhances users' Internet browsing experience by providing shortcuts to share selected text, photos, etc., on social networks and email. Whilst quick sharing features such as these may appear useful, QuickShare is not considered as a legitimate browser add-on, since many computer users report that it was installed on their Internet browsers without their consent. Moreover, this browser plug-in causes unwanted coupon ads when visiting online shopping websites. Unwilling installation of QuickShare is often caused by reckless free software download and installation.

QuickShare adware

This potentially unwanted program is distributed using a deceptive marketing method called 'bundling'. Computer users, who do not pay close enough attention to freeware installation steps, may install this or other unwanted additional programs inadvertently. QuickShare is compatible with Internet Explorer, Google Chrome, and Mozilla FireFox. Note that this browser extension is not technically considered a virus, however, installation is often inadvertent or unwilling, and furthermore, this plug-in displays coupons ads and may cause privacy-related issues.

QuickShare is similar to other potentially unwanted programs such as InfoAtoms, QwikLinx, and many others. Note that having additional unwanted browser plug-ins installed on Internet browsers may cause security, privacy, and browser performance issues. To prevent installation of browser extensions such as this, download free software from legitimate sources, and always choose 'Custom Installation', rather than 'Typical Installation' when installing freeware. Never agree to installation of additional promoted software, and disallow any suggested changes (homepage, default search engine, etc.) to your Internet browser settings. To remove QuickShare, use the removal guide provided.
