How to uninstall the Digeus Registry Cleaner?

What is Digeus Registry Cleaner?
Digeus Registry Cleaner is the name of a program that is supposed to scan Windows registry for invalid information, remove invalid entries and improve computer performance and stability.
Although, it is distributed using questionable methods which means it is likely that users may download and install unintentionally. Programs that users download and install without knowing about it are called potentially unwanted applications (PUAs).
The Windows Registry is a database that stores settings for the Windows operating system and for programs that use the registry. The Digeus Registry Cleaner is supposed to fix registry entries causing error messages, unexpected system crashes and slowing down a computer.
Digeus Registry Cleaner is not a free program - the unregistered version is limited to fix only up to 5 entries per scan. The important thing about PUAs that are supposed to fix registry errors, remove viruses and solve other problems is that not all of them are trustworthy.
More precisely, there are many PUAs designed to display fake scan results to trick users into purchasing their full (registered, activated) versions. Digeus Registry Cleaner may not be running fake scans. However, it is categorized as PUA, and apps of this kind should not be trusted. Also, it is common that their installers have additional offers in them.
For example, they are bundled with browser hijackers, adware-type apps. Browser hijackers are designed to change the browser's settings to promote a fake search engine.
Usually, apps of this type change the address of a default search engine, homepage, and new tab to an address of a fake search engine and prevent users from undoing those changes unless they uninstall those apps. Fake search engines can generate misleading results.
Therefore, they should not be used. Adware generates ads that can be designed to open suspicious websites or download or even install unwanted software by executing certain scripts.
Both browser hijackers and adware-type apps can function as data collectors designed to gather geolocations, addresses of visited websites, entered search queries, IP addresses, etc., or even sensitive information. It is important to mention that data collected by PUAs is likely to be misused for malicious purposes, e.g., it could be sold to third parties (potentially cybercriminals), used for marketing purposes, or be monetized in other ways.

It is common that users have to activate, register (purchase) these programs in order to use all their features. It is highly advisable not to pay money for potentially unwanted applications or even have them installed on browsers or computers.
How did potentially unwanted applications install on my computer?
Most users download and install potentially unwanted apps through deceptive advertisements or together with other programs. It is common that PUAs are included in downloaders or installers for other programs as extra offers.
This distribution method is called "bundling". In most cases, bundled applications can be deselected (opted out) via "Custom", "Advanced" or similar settings, or by unticking checkboxes that downloaders, installers have. When users download or install programs without checking (and changing) those settings agree to download or install included apps as well.
As mentioned at the beginning of this paragraph, unwanted downloads (and installations) can be caused through deceptive advertisements. Users cause them by clicking ads that are designed to run certain scripts.
How to avoid installation of potentially unwanted applications?
Files and programs downloaded from questionable sources like Peer-to-Peer networks (e.g., eMule, torrent clients), unofficial pages, third-party downloaders, and so on, or installed using third-party installers should not be trusted. It is common that such channels are used to distribute unwanted, or potentially malicious software.
All files, programs should be downloaded from official websites and through direct links. Furthermore, it is recommended not to finish downloads and installations without declining unwanted offers.
Usually, downloaders and installers that are bundled with PUAs have settings like "Custom", "Advanced", or checkboxes. Those settings can be used to decline unwnanted offers.
Advertisements on shady, questionable pages should not be clicked. Quite often, those ads are designed to open untrustworthy pages. Sometimes they can cause unexpected downloads, installations.
All unknown, suspicious extensions, plug-ins or add-ons installed on a browser and software of this kind installed on the operating system should be uninstalled. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
