How irritating is this problem? (6 votes, average: 5.00)

This page aims to help you remove Chameleon Explorer. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

In the next article, the readers of this post will be introduced to a PC program named Chameleon Explorer Pro. On the outside, it appears to be a useful file-manager tool that adds a number of neat functions to your Windows Explorer which help you navigate folders more quickly and more efficiently. However, although this program might seem useful and helpful, there are certain features or traits that it seems to possess which might actually lead to its categorization as a PUP – a potentially unwanted program. But what is a PUP? Well, PUPs are pieces of software – programs, apps, software tools and so on, that are typically not harmful for the user’s system. They are not like viruses (Trojans, Ransomware, Spyware, etc.) and would hardly ever threaten to harm your computer in any given way. That said, they are regarded as unwanted due to certain traits that they might have which make their presence on the computer unpleasant. One of the best examples of a feature/trait that would make a given piece of software unwanted is its use of intrusive ads. There are indeed many programs out there (a lot of which quite useful) that are still seen as PUPs due to their tendency to spam the user’s screens with obnoxious and highly irritating advertising materials such as banners, pop-ups, blinking boxes, flashy online message requests and so on and so forth. Some PUPs also try to gather telemetry data from your PC and browser to make their targeted advertising more accurate and effective. It’s even possible that a potentially unwanted program tries to impose alterations to your machine’s settings by tinkering with its Registry Editor and modifying different Registry keys or by making changes to your default browser. There are indeed many ways a PUP could negatively affect your PC system despite not directly harming it.

Back to Chameleon Explorer Pro

So, why is Chameleon Explorer Pro seen as a PUP? Well, according to a number of reports from disgruntled users, this piece of software tends to put irritating advertising materials on their screen whenever it is active on the PC which, in turn, makes it rather irritating and difficult to use the computer normally. The could come in all shapes and sizes and are sure to nag you with their presence until you try to manually close them. This, however, is something we’d advise you not to do because it might simply result in you getting redirected to some obscure website whence the ad came. The reason this might not be the best scenario has to do with the risk of actually landing on some dangerous and unreliable website. PUPs, for the most part, are not as dangerous as, say, a Trojan Horse virus or a Ransomware infection. However, through their ads, they might indeed indirectly compromise the safety of your machine as you could never be fully certain that a given ad wouldn’t land you on some hazardous webpage that is being used for malware distribution. That is why, it’s best if you find a way to cease the ads generation so that there would no longer be any risk of getting redirected to random websites that you might not want to visit.

So, how to stop the ads?

Well, since in this particular case, the Chameleon Explorer Pro application seems to be the main cause of the ads generation, the best way to make the adverts go away would be by removing the program that is causing their appearance. Now, some of you might actually find Chameleon Explorer Pro as an useful tool and that’s perfectly fine. As we said in the start of this post, many PUPs are actually rather helpful program that unfortunately possess some unpleasant trait which makes them unwanted. In the case of Chameleon Explorer Pro, it is up to each and every one of you to decide whether keeping the program is worth the irritation and the potential risk of landing on some sketchy site or if it you’d be better off uninstalling the PUP.

In case you decide to go for the latter option, you can find a useful removal guide on this page that can help you eliminate the nagging app and make its ads stop appearing on your screen. As far as avoiding PUPs in the future is concerned, make sure you always use sources for new software that are reliable and also that you always check the Advanced installation settings and use them to install new programs so that you could manually leave out any bonus components that might be categorized as PUPs.
