This page aims to help you remove Chrome Cleaner Pro “Virus”. Our removal instructions work for every version of Windows and Mac, as well as Android.

In the following article, you will be introduced to a Google Chrome extension known as Chrome Cleaner Pro. The first thing important enough to highlight right away – although some users and researchers regard it as a Virus, Chrome Cleaner Pro is actually a PUP (potentially unwanted program). We will elaborate upon the possible issues that some customers have reported about this Chrome add-on and will explain why it might be considered a PUP.

It is no secret that the Google Chrome browser is one of the most popular and widely used browsing programs nowadays. It is fast, secure,versatile and offers a wide variety of customization options. However, despite it’s high effectiveness, one could still potentially encounter certain issues with Chrome that could make their online experience less pleasant and optimized. One such common problem is when the browser starts getting slowed-down over time. There are many reasons that can cause that – a build-up of temporary cache files, cookies, a lot of unneeded extensions and downloads, etc. This has lead to the development of different software applications that are supposed to work as browser optimization tools in order to improve the performance and speed of the browser. One such program is the object of today’s article – Chrome Cleaner Pro.

Chrome Cleaner Pro

According to its developers, it is a simple Chrome extension that can make the browser work faster, free disk space on the PC (likely by deleting unneeded browser-related files) and make the online privacy of the user more secure. All of this sounds pretty good and straight forward so why is Chrome Cleaner Pro considered to be PUP by some users and researchers?

Online advertising

Online advertising/marketing is currently a thriving business and everybody strives to get a piece of it. A lot of software developers rely on ads to either promote or support their products and, as it seems, the people behind Chrome Cleaner Pro are no exception. Though most of the reviews for this application seem to be positive, there are still quite a few of users who claim that Chrome Cleaner Pro has tried to introduce unwanted changes to their Chrome browser. The most notable of those changes are the replacement of their homepage and/or new-tab page with some sponsored site/search engine. Though this isn’t a big deal, it is still unpleasant when some program tries to alter the settings of your browser without asking for you permission first. In fact, this is a trait that is typical for a software category known as browser hijackers yet, since Chrome Cleaner Pro seems to be less intrusive than most typical hijackers, we will not refer to it as such in this article. That said, it can still be pretty annoying to have your Internet/browser settings modified in such a way. Also, in addition, it is possible that the PUP might also try to display ads on your screen that could also be irritating which is another potential issue that you might encounter with this software utility.

In terms of how well Chrome Cleaner Pro does its job, some users claim that it has indeed managed to improve the work of their browsers. However, here we must note that in the majority of cases, one could manually do a lot of the things that most such optimization tools are typically used for. For instance, you don’t really need any kind of specialized software to clean your browser’s cache, history, unneeded downloads, cookies and other similar components. Furthermore, it isn’t even that difficult or complicated to do it yourself. In Chrome’s case, all you have to do is open the browser’s menu, go to Settings > Advanced, find Clear browsing data, click on it, then tick all the boxes and select Clear Data. This will clean most of the components that the extension in question offers to clean automatically and will also free some HDD space as well.

Here, we must make a sidenote regarding the freed disk space. Even if Chrome Cleaner Pro manages to free some space on your hard-drive, it won’t be anything above 1-2 GB of storage space and since most modern PCs (even low-end ones) have at least 500 GB hard-drive memory, the amount of storage space that can be freed by cleaning your browser is pretty much negligible.

In terms of privacy, we can’t really say how much protection this extension can offer considering the fact that Chrome is already one of the safest and most secure browser programs out there. Also, there’s pretty much no explanation in the add-on’s description how it actually would supposedly make your browser more secure.

Distribution of Chrome Cleaner Pro

Typically, users can get this Chrome extension from the Google webstore. However, with such PUPs it is not uncommon that they could also get distributed via file bundles where the add-on is added to an installation package where there’s one main program and one or more added applications that are optional. If you want to avoid getting such optional applications on your PC when trying to install a certain program, always remember to carefully examine the setup menus and seek settings that would allow you to customize the installation. Once you find such settings, make sure to uncheck all optional clauses that offer to install some other software on your PC that you might not really want. After doing so, you should be good to go and launch the installation of the main program (the one that you do want to install).
