Type: Potentially Unwanted Application

One Click Booster

One Click Booster is a PC optimizer that is said was designed “to keep your PCs running smooth, fast and error free.” Instead of trusting the software’s descriptions, it is wiser to test it and see it for yourself what it is capable of. Unfortunately, the application’s trial version does not allow fixing issues for free after it scans the system, so it is difficult to say how beneficial it might be. Another thing you should know is that the tool falls under the category of potentially unwanted programs also called PUPs. It does not mean it is malicious, although it may have undesirable qualities that could make users wish to uninstall it. If you came here to learn how to remove it, you should slide below the text and use our provided deletion instructions. Nonetheless, to avoid similar software in the future and learn more details about the PUP, we recommend reading our full report first. In it, we will talk about how One Click Booster works, how it might be distributed, and so on.

One Click Booster comes from a site called We believe users could come across it while interacting with pop-ups or advertisements alike. If you want to avoid PUPs, you should understand that installing a program after reading its description alone is never a good idea. First, it would be wiser to find out if a reputable company developed the software. Also, we recommend reading expert reviews or comments from users who already tested the application. Of course, you should not trust user reviews blindly since some of them can be fake. There are browser hijackers, adware, and PUPs with fictitious comments praising the software to convince others to install them. Thus, you should always think about whether the comment sounds natural as well as check if the user who created it exists. For example, on Chrome Web Store page you can click on the user’s avatar and see his Google profile; if it is empty, it is possible it could be fake.

During the installation, some users may install an additional application that is not related to One Click Booster without realizing it. The offered tool is called Driver Updater, and we believe it could be a PUP as well. Users might not understand they do not have to install it because the window on the setup wizard showing the suggestion says “we recommend “Driver Updater” to improve system performance” and since the application itself also promises to improve the computer’s performance it may look like the offered tool is its component. Not to mention instead of displaying buttons that would clearly show the user he can skip the suggested program or agree to install it, the setup wizard provides a “Continue” button. It has a blue borderline to make it more visible and no doubt those who do not pay attention to the installation process might think the “Continue” button means they are still installing the same program.

Furthermore, when One Click Booster gets installed, the PUP ought to scan the computer to detect issues that are supposed to be the reason for the slow computer’s performance. Truth to be told, our researchers doubt the identified problems can influence the system's performance enough to make slower it. We do not say the applications shows fake scan results; it is just the issues it may detect might be nothing more than leftovers that could have piled up after uninstalling applications over time. Such leftovers are usually found in the Windows Registry, and most of the software’s located issues were invalid Registry files when we tested it. Moreover, earlier we mentioned One Click Booster might have undesirable or annoying qualities. What we had in mind is that the PUP could urge the user to deal with the detected issues. Nevertheless, when you click the fix issues button, it should ask you to buy the tool’s license.

While the software’s creators have every right to ask for a payment for something they have developed, it is strange the user is not allowed to test it first to make sure the application is as useful as described. After all, it is unlikely the one-time removal could be a permanent solution. If you think the tool should provide one free removal so you could test it before purchasing it, and you do not want to buy it without testing it, you should look for a program that offers it.
