What is PC Cleaner Perfect?
PC Cleaner Perfect is advertised as a tool that cleans unwanted data stored on a computer to optimize its performance. It is known that this program is promoted using questionable methods. Therefore, it is likely that users could install PC Cleaner Perfect unknowingly. Apps that users install inadvertently are called potentially unwanted applications (PUAs).
PC Cleaner Perfect is supposed to clean Registry, Windows logs, startup items to improve computer performance. PC Cleaner Perfect allows users to scan the operating system for unwanted entries but does not remove them unless users register it (enter a purchased registration/activation key.
It is important to mention that potentially unwanted applications can be designed to run fake scans. The main purpose of such PUAs is to trick users into believing that after purchasing a full version, they will be able to improve computer performance, remove unwanted (or even malicious) programs, etc.
In conclusion, it is strongly recommended not to pay money for programs like PC Cleaner Perfect - they are likely to be useless (run fake scans without actually removing any unwanted entries or fixing other problems). Another important detail about PUAs is that they often are distributed together with adware, browser hijackers, and other apps of this kind.
Adware-type applications display pop-up ads, banners, surveys, coupons, and other unwanted (and annoying) advertisements. It is common for those ads to be designed to open questionable websites. In some cases, those ads cause unwanted downloads or installations by running certain scripts.
Browser hijackers promote fake search engines by changing settings such as the address of a default search engine, homepage, and (or) new tab, and do not allow users to remove the address of a fake search engine from those settings as long as they are installed. Another issue with adware-type apps (and browser hijackers) is that they can be designed to collect data.
Apps of this kind can be designed to collect IP addresses, entered search queries, visited websites, and other browsing data. However, they can be designed to gather passwords, credit card details, and other personal information as well. Therefore, it is strongly recommended not to have any browser hijacker or adware-type app installed on a browser or computer.

PC Cleaner Perfect is supposed to function as a system optimized. However, it is likely that it does not remove any unwanted entries and is simply designed to trick users into registering it (into paying money for its activation/registration). More examples of programs categorized as PUAs are PC Accelerator, Fix PC, and Digeus Registry Cleaner.
How did potentially unwanted applications install on my computer?
More often than not, users download or install potentially unwanted applications together with free programs. It is common for PUAs to be distributed by including them in downloaders or installers as optional offers. Users agree to download or install offered PUAs when they leave certain settings unchanged.
Typically, downloaders or installers that include extra offers have "Advanced", "Custom", "Manual" or other settings, or ticked checkboxes. Users can use those settings to deselect offered PUAs. In some cases, users cause unintentionally cause unwanted downloads or installations by clicking advertisements designed to execute certain scripts.
How to avoid installation of potentially unwanted applications?
Downloaders and installers that have checkboxes or settings like "Custom", "Advanced," and other settings often are used to distribute PUAs. It is recommended to check those downloaders, installers for optional offers and decline them before finishing downloads and installations.
Programs and files should be downloaded from official websites and via direct links. It is common for other sources like Peer-to-Peer networks (torrent clients, eMule and similar networks), unofficial websites, third party downloaders, installers to be used as channels to distribute PUAs.
Advertisements that appear on shady websites should not be trusted as well. Quite often, those ads are designed to open untrustworthy websites or download, install unwanted apps. Unwanted, suspicious extensions, add-ons, or plug-ins that are installed on a browser should be removed.
The same should be done with programs of this kind that are 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.
