What is CleanMyPC?
CleanMyPC is advertised as a program which cleans and optimizes the operating system and improves computer performance. In fact, it is distributed by using dubious methods and, therefore, CleanMyPC is categorized as a potentially unwanted application (PUA). Users often download and install these apps inadvertently.
CleanMyPC supposedly cleans junk files, removes unwanted programs installed on the computer and extensions installed on the browser, cleans the system registry, and includes various other features. In fact, to use any 'features', users must pay for activation.
PUAs do not function as promised or fix any genuine issues - they provide fake scan results to trick people into paying for activation. It is unknown whether CleanMyPC functions in this way, however, there is a strong possibility that it does. Note that installers of apps such as CleanMyPC can also be used to distribute other PUAs (e.g., adware, browser hijackers).
Adware is a type of software that serves coupons, banners, surveys, pop-ups and other advertisements. The ads can promote (open) untrusted websites or even run scrips designed to download and install unwanted programs. Browser hijackers are PUAs that promote fake search engine addresses by changing certain browser settings.
Note that adware-type apps and browser hijackers often gather browsing data (e.g., IP addresses, geolocations, entered search queries, addresses of visited websites, and so on). Some apps of this type are capable of accessing sensitive information as well.
The data could be sold to third parties (potentially, cyber criminals) or misused to generate revenue in other ways. Therefore, remove all PUAs from browsers and operating systems immediately, including CleanMyPC.

How did potentially unwanted applications install on my computer?
Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that at a proportion of users inadvertently download and install them together with their chosen software.
This distribution method is known as "bundling". Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default.
Unwanted downloads and installations are also sometimes caused by clicking deceptive advertisements capable of executing certain scripts.
How to avoid installation of potentially unwanted applications
Software and files should be downloaded from official sites and via direct download links. Other sources/tools such as third party downloaders, Peer-to-Peer networks (for example, torrent clients, eMule), unofficial websites should not be used, as they can download and/or install unwanted, malicious software.
Third party installers can also to distribute unwanted software. Check all "Advanced", "Custom" and other settings, and decline offers to download or install PUAs. Remove any unwanted, suspicious extensions, plug-ins, and add-ons that are already installed on the browser, and programs of this kind that are installed on the computer.
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
