QuickShare - how to eliminate unwanted coupon ads?

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.

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 adware

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.

A browser hijacker is a type of adware that alters user's Internet browser settings by changing one's homepage and default Internet search engine to some unwanted website. Most commonly this type of adware infiltrates user's operating system through free software downloads. While browser redirects might seem as a low risk security infection, computer users should know that the websites to which they are being redirected to commonly contain deceptive online advertisements and the Internet search engine that is presented in such websites might return shady Internet search results. Using such websites for one's daily Internet searches might easily end up in privacy issues, identity theft or malware infections.

A computer that is affected by a browser hijacker is exposed to high risk security infections. To prevent further privacy and security issues it's recommended removing any Internet browser settings altering adware as soon as possible.

My Firefox got infected with this. I also found it buried in IE masking as Linkury.

I was concerned about messing up my pc.

Could not find anything in "add/remove programs".

The realised a program, Revo Uninstaller I downloaded some time ago just might work.

Amazingly this worked a treat. There are four levels available and I used #4 which is the slowest but deepest removal.

When you activate it it displays all installed programs, stuff that does not appear in "add/remove".

Revo Uninstaller was free but it's fantastic!
