PC Optimizer Pro removal instructions
What is PC Optimizer Pro?
PC Optimizer Pro is advertised as the best free PC optimization software. However, it is very likely that this application is distributed using questionable methods, which means it is possible that there could be users who would download and install it unknowingly. Apps that users download and install unintentionally are categorized as potentially unwanted applications (PUAs).
PC Optimizer Pro is designed to run a system scan that checks it for invalid registry entries, junk files like temporary files, broken shortcuts, browser's cache, cookies, and other items. Nevertheless, users cannot remove found items unless they purchase the full version of the PC Optimizer Pro. Moreover, since this app is likely to be a PUA, it may generate fake scan results. Simply said, it may be designed to trick users into purchasing it and not actually improve PC performance even after being registered (upgraded to a full/paid version).
Also, it is possible that some browser hijacker, adware-type app, or unwanted app of other type is distributed alongside PC Optimizer Pro. Browser hijackers promote fake search engines (their addresses) by changing browser settings without user's permission. Usually they modify settings such as the address of a default search engine, homepage and new tab, and do not allow to undo those changes unless users uninstall them. Adware is a type of software that generates ads, for example, coupons, banners, surveys, pop-ups and/or ad of other types. Quite often those ads are designed to open (promote) dubious pages, or even download and/or install unwanted apps by running certain scripts.

How did potentially unwanted applications install on my computer?
Users relatively often download and/or install potentially unwanted apps through setups of other programs - when PUAs are included in download and/or installation setups of those programs as additional offers. Usually users can decline unwanted offers via "Custom", "Advanced", or other settings, or by unticking certain checkboxes. Users allow for PUAs to be downloaded or installed together with other programs when they lave default settings of setups unchanged. This distribution method for PUAs is called "bundling". Also, unwanted downloads or installations can be caused by clicking deceptive advertisements. There are deceptive ads that, if clicked, would run scripts that are designed to cause unwanted download, or even installation.
How to avoid installation of potentially unwanted applications?
Software should not be downloaded (or installed) through third party downloaders (or installers), Peer-to-Peer networks like eMule, torrent clients, unofficial pages, and so on. We recommend to download it using only official websites and direct download links. Furthermore, if a setup contains "Custom", "Advanced" and other similar settings, then they should not be left unchecked. They often contain offers to download or install unwanted software that can be dismissed before completing download or installation process. Intrusive ads (especially when displayed on shady pages) redirect people to potentially untrustworthy sites or download, install unwanted apps. For these reasons it is recommended not to trust and click them. Also, we recommend to uninstall all unwanted extensions, plug-ins or add-ons that are installed on a browser and programs of this kind that are installed on a computer. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
