KNCTR Unwanted Application

Also Known As: KNCTR potentially unwanted application
Type: Utilities
Damage level: Low

What is KNCTR?

Developed by Itibiti Ventures Inc, KNCTR is a rogue application claiming to allow users to make calls free of charge, connect to popular social networks (Facebook, Twitter, etc.), and enable other functions.

While this functionality may seem legitimate and useful, be aware that KNCTR is categorized as a potentially unwanted program (PUP), since it employs a deceptive software marketing method called 'bundling' (stealth installation of additional programs with the chosen software) to install on computers without users' consent.

Following successful infiltration, KNCTR monitors browsing activity by collecting various software and hardware information such as IP addresses (to determine users' geographic locations), browser information (cookies, web beacons, URLs visited, pages viewed, etc.), and other similar details.

KNCTR adware

At time of testing, this application was mostly distributed via small download programs (called 'installers', 'download clients', download managers', etc.) employed by freeware download websites such as download.com, softonic.com, and soft32.com.

These programs are used to monetize website free services and traffic by offering installation of promoted (according to the developers, '100% legitimate') applications with the chosen free software. Thus, download and installation of freeware often results in adware or malware infections including Genesis, Offer Boulevard, Hahomedia, or in this case, KNCTR.

Although these applications claim to enable various useful functions, they actually diminish computer performance and may cause high-risk system infections. The real purpose of these PUPs is to generate revenue by the display of intrusive online advertisements or by enforcing unwanted browser redirects.

Installation of KNCTR (or other similar potentially unwanted programs) can be avoided by closely studying each step of the free software download procedure and clicking 'Decline' if installation of any additional applications is offered.

Furthermore, all software downloaded from the Internet should be installed using the 'Advanced' or 'Custom' installation options, rather than 'Quick' or 'Regular' - this will reveal any bundled applications listed for installation and allow you to opt-out.

If you have unwillingly installed KNCTR, follow the removal instructions provided to uninstall this potentially unwanted program from your computer.
