How to uninstall the One Click Booster potentially unwanted application?
Written by Tomas Meskauskas on (updated)
What is One Click Booster?
On its website, One Click Booster is presented as software designed to clean, speed up and optimize Windows computers. This may seem a legitimate and useful tool, however, developers promote it using the "bundling" method. Therefore, many people install this software unintentionally or accidentally.
Therefore. One Click Booster is categorized as a potentially unwanted application (PUA).
One Click Booster overview
One Click Booster allows users to perform a scan that, once finished, will indicate any malicious programs, errors on the operating system, registry issues, and so on. To fix problems, uninstall unwanted programs, remove threats and so on, activation is required. The 'free' version, however, is only capable of detecting issues, not solving them.
Note that applications promoted using the "bundling" method cannot be trusted. There are many system optimization-related (and other) PUAs that display fake results. They encourage people to purchase the software by making them believe that there are problems with their PCs.
It is unknown whether One Click Booster is one of these apps, however, most apps of this type (potentially unwanted apps that are promoted via "bundling" method) carry out these actions. Furthermore, this method is often used to promote more than one unwanted application at once.
Typically, apps of this type are installed together with various browser hijackers or adware-type apps. If installed, these apps feed users with intrusive advertisements (coupons, banners, surveys, pop-ups, and so on) and collect information relating to users' browsing habits.
Generally, having apps of this type installed can lead to problems relating to browsing safety, privacy, and so on. We recommend that you uninstall One Click Booster and other unwanted, unintentionally installed applications or programs immediately.

Potentially unwanted application examples
One Click Booster is similar to other programs of this type including, for example, Registry Scanner, Lowe Registry Cleaner, Power PC Care 2018, and a number of others.
As mentioned above, most of these apps are presented as useful and legitimate, however, they are promoted using the "bundling" method and many do not provide users with any real value or the functions promised.
How did potentially unwanted applications install on my computer?
One Click Booster's developers promote this PUA using a website from which it can be downloaded, however, most people install PUAs through intrusive ads (clicked ads that download/install unwanted applications) or when software developers use "bundling", a deceptive marketing method used to trick people into downloading and installing PUAs together with other software that was downloaded/installed willingly.
They hide these rogue apps in "Custom", "Advanced" and other similar settings of software download or installation set-ups. Information regarding the inclusion of unwanted apps is not properly disclosed. Therefore, people who rush installations, without studying them carefully often cause unwanted installations.
How to avoid installation of potentially unwanted applications?
Software should be downloaded from official websites and using direct links. Do not use third party downloaders, unofficial websites, Peer-to-Peer networks, and other similar channels. These tools are often monetized by promoting unwanted applications, which can also cause computer infections.
Install/download software with care: pay enough attention to details of each software download and installation setup. Check "Custom", "Advanced" and other available options. Deselect offers to download or install PUAs. Do not click intrusive ads, especially when they are displayed on unofficial, dubious websites.
If clicked, they might cause redirects to gambling, pornography, adult dating, and other similar, untrustworthy websites. If these redirects occur without clicking ads, or ads of this type appear on all visited websites, this is likely to be due to PUAs installed on the system. We advise you to check the list of installed browser apps (extensions, plug-ins and add-ons).
Remove any unwanted entries immediately. The same applies to programs installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
