What is Unfriend List?

The Unfriend List application supposedly warns users when someone 'unfriends' them on Facebook - "See Who Unfriended You. With Facebook Unfriend List. Because knowing who your friends are is just as important as who aren't your friends."

These claims may trick some users into believing that Unfriend List is a legitimate and useful application, however, it is classed as adware and a potentially unwanted program (PUP). Following successful infiltration, Unfriend List tracks Internet browsing activity and displays intrusive online advertisements.

Unfriend List adware

The rogue app continually monitors users' Internet browsing activity and collects various software and hardware information that may be personally identifiable. This information is stored on a remote server, later shared with third parties, and might later be misused to generate revenue - thereby causing serious privacy issues or even identity theft.

In addition, Unfriend list displays various intrusive advertisements such as banner, pop-under, and pop-up ads. These delivered ads conceal the underlying content, diminishing users' Internet browsing experience. They may also redirect to rogue websites containing infectious content.

There is a high probability that clicking them will lead to further computer infections, and therefore, you are strongly advised to uninstall Unfriend List from your system immediately.

Unfriend List claims regarding online advertising:

Unfriend List is entirely free to use, but may show advertisements while installed. These promotions help us keep Unfriend List awesome and free for you.

Although Unfriend List is identical to Unfriend Watch, there are hundreds of other applications that share many similarities. For instance, Computer Pal, iWebar, Shopperz, and RightCoupon also claim to offer 'useful' features. In fact, none (including Unfriend List) provide the functionality promised.

As with many other adware-type applications, Unfriend List is developed to generate revenue for the developers by displaying advertisements and sharing collected data with third parties. It provides no real value to the user.

How did Unfriend List install on my computer?

Adware-type applications such as Unfriend List are usually distributed using a deceptive software marketing method called 'bundling' - stealth installation of additional programs with regular software.

Many users do not pay enough attention when downloading and installing software, and thus, bundling becomes a very effective method. Users often skip most of the download and installation procedure steps, unaware that rogue apps are concealed within the 'Custom' or 'Advanced' settings. In this way, they inadvertently install rogue applications.

How to avoid installation of potentially unwanted applications?

Installation of apps such Unfriend List can be avoided by taking a number of simple measures. Closely observe the download procedure of all software and opt-out of any bundled applications. Furthermore, installation of programs should be performed with the 'Custom' or 'Advanced' settings - this will reveal any third party programs listed for installation and allow you to opt-out.
