Junk Cleaner PUP

What is Junk Cleaner?

Junk Cleaner is a deceptive app claiming to significantly improve the computer’s 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, such software might actually seem appropriate and handy, however, the truth is that Junk Cleaner is considered as a potentially unwanted program (PUP) and an adware. Not only it infiltrates the system without asking for users’ permission, but also generates fake error messages.

Junk Cleaner adware

Although Junk Cleaner claims to improve the computer performance, this is actually false. The application continually generates fake error messages stating that computer has been infected or either encountered certain problems. What’s more, these errors encourage users to contact the developers via provided phone number (1-866-606-9133) in order to solve these problems. Once users call the provided phone number, they’re asked to pay a certain amount of money in exchange for help. However, users can never be sure that they’ll receive the help. Therefore, paying is equivalent to sending the money to cyber criminals – you simply support their malicious business. This kind of behavior is very common for an adware-type applications (for example MovieDea and GamesDesktop), fake error messages are also displayed by rogue antivirus programs.  We strongly advise you to ignore these errors and uninstall Junk Cleaner as soon as possible.

There are hundreds of potentially unwanted programs similar to Junk Cleaner, for example, SwiftSearch, MapsWorld, DesktopClock. The only difference is that regular adware-type apps usually display advertisements (using ‘Pay Per Click (PPC)’ advertising model) and collect personally identifiable information (which is later sold for third party companies). Yet every single adware claims to provide various useful features just to trick users into installation. However, users must be informed that their true purpose is to generate earnings for the developers. Therefore, neither Junk Cleaner, nor any other adware actually enables the promised functionality.

How did Junk Cleaner install on my computer?

Users are able to download Junk Clear at it’s official website. However, this application is most likely to be distributed as a bundle along with other applications (usually free). Bundling is basically a stealth installation of third party applications along with the regular ones. What developers do is conceal potentially unwanted programs within ‘Custom’ or ‘Advanced’ settings. The problem is that most of users recklessly skip this section, what often ends up in an inadvertent installation of bogus applications, such as Junk Cleaner. The developers are only concerned with amount of generate income, which is dependent on the actual number of distributed PUPs, hence, they intentionally hide them.

How to avoid installation of potentially unwanted applications?

The only way to safely download and perform the desired software is to pay close attention during both of these processes. Always make sure to select either ‘Custom’ or ‘Advanced’ settings, because potentially unwanted programs, that must be canceled, are usually hidden. Every user should know that the key to computer safety is caution, hence, they should never rush when downloading and installing software.

Most commonly adware or potentially unwanted applications infiltrate user’s Internet browsers through free software downloads.
