How to remove the Jet Cleaner potentially unwanted application?
Written by Tomas Meskauskas on (updated)
What is Jet Cleaner?
Jet Cleaner is a piece of software promising to clean and optimize the performance of operating systems. Due to the dubious methods used to distribute it, this app is classified as a PUA (Potentially Unwanted Application). Software within this classification can have undesirable/harmful abilities and/or be promoted alongside such applications.
Potentially unwanted application overview
While questionable distribution methods can be used to endorse legitimate products, they are more commonly used to spread untrustworthy software like PUAs.
Unwanted apps typically appear innocuous and offer "handy" functionalities that rarely work as advertised, and in most cases - they are utterly nonoperational. Fake anti-viruses are a prime example of this; they require activation (i.e., purchase) to operate, yet afterwards - remain nonfunctional.
Additionally, PUAs often have undesirable and even dangerous abilities. Jet Cleaner has been observed force-opening various (potentially dubious and even malicious) websites. Other popular PUA types include advertisement-campaign running adware and browser modifying/ fake search engine promoting browser hijackers.
What is more, many PUAs can track data. They can monitor browsing activity (visited URLs, viewed pages, searched queries, etc.) and gather vulnerable information extracted from it (IP addresses, personally identifiable detail, finance-related data, etc.). The collected information is monetized by being shared with and/or sold to third-parties.
To summarize, the presence of unwanted apps on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft.

Potentially unwanted application examples
PC Cleaner Perfect, PC Accelerator, Fix PC, and Telamon Cleaner are some examples of applications akin to Jet Cleaner. The sole goal of unwanted software is to generate revenue for the developers; hence, functionality and user safety are irrelevant. Therefore, the presence of PUAs on devices - endangers system integrity and user privacy.
How did potentially unwanted applications install on my computer?
Select PUAs (e.g., Jet Cleaner) have "official" promotional/download webpages. These apps are most commonly spread using the "bundling" marketing tactic - packing regular programs with unwanted/malicious additions. By rushing through downloads/installations (e.g., skipping steps, using pre-set options, etc.), users risk allowing bundled content into their devices.
Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to make stealthy downloads/installations.
How to avoid installation of potentially unwanted applications?
It is highly recommended to research software and only download from official/verified channels. Untrustworthy sources, e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled and hazardous programs/media.
When downloading/installing, it is advised to read terms, study possible options, and use the "Custom/Advanced" settings to opt-out from all supplements. Intrusive adverts appear legitimate, yet they redirect to dubious sites (e.g., gambling, pornography, adult-dating, etc.).
Should users encounter ads and/or redirects of this kind, they must check their devices and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
