What is Junk Cleaner?

Junk Cleaner is a deceptive app claiming to significantly improve computer performance - "Junk Cleaner is one of the finest PC performance tools available in the market today, when it comes to improving performance and speed of your PC. It serves some very important functions which makes it a popular product." On initial inspection, this software might seem legitimate and useful, however, Junk Cleaner is classed as a potentially unwanted program (PUP) and adware, since it infiltrates systems without users' permission and generates fake error messages.

Junk Cleaner adware

Although Junk Cleaner claims to 'improve computer performance', this statement is false. The application continually generates fake error messages stating that the system is infected or has encountered certain problems. Furthermore, these messages encourage users to contact the developers via the telephone number provided (1-866-606-9133) to solve these problems. When users call the number, they are asked to pay a specific amount to receive assistance. In fact, users cannot be sure that they will receive any help. Therefore, paying is equivalent to sending your money to cyber criminals - you will simply support their malicious business. This behavior is common to many adware-type applications (including, for example, MovieDea and GamesDesktop). Fake error messages are also displayed by rogue antivirus programs. We strongly advise that you ignore these message and uninstall Junk Cleaner immediately.

There are hundreds of PUPs similar to Junk Cleaner including SwiftSearch, MapsWorld, and DesktopClock. The only difference being that regular adware-type apps usually display advertisements (via the 'Pay Per Click' [PPC] advertising model) and collect personally identifiable information (which is later sold to third party companies). All adware claims to provide various useful features to trick users to install, however, the true purpose of these PUPs is to generate revenue for the developers. Neither Junk Cleaner, nor any of these other adware-type apps, provide the functionality promised.

How did Junk Cleaner install on my computer?

Users are able to download Junk Clear on its official website, however, this application is commonly distributed as a 'bundle' with other (mostly free) applications. Bundling is stealth installation of third party applications with regular software. Developers conceal PUPs within the 'Custom' or 'Advanced' settings. Many users skip this section, which leads to inadvertent installation of bogus applications such as Junk Cleaner. The developers are concerned only with the amount of revenue generated, which is dependent on the number of PUPs distributed, and hence, they intentionally hide them.

How to avoid installation of potentially unwanted applications?

The only way to safely download and install your chosen software is to pay close attention during these processes. Select the 'Custom' or 'Advanced' options - this will reveal any hidden PUPs and allow you to cancel them. The key to computer safety is caution. Never rush when downloading and installing software.
