How to uninstall the Registry Cleaner potentially unwanted application (PUA)
Written by Tomas Meskauskas on (updated)
What is the Registry Cleaner PUA?
Registry Cleaner is untrusted software endorsed as a tool for cleaning, repairing and optimizing the operating system by managing registry files. Due to the dubious methods used to proliferate Registry Cleaner, however, it is classified as a Potentially Unwanted Application (PUA).
PUAs are often unable to operate as advertised and can have harmful capabilities that are not declared.
Dubious distribution techniques can be used to promote legitimate software, yet these tactics are more commonly employed to proliferate unwanted and even malicious programs. PUAs typically seem normal and innocuous. They can also offer a wide variety of "useful" functionality, however, the features rarely work as promised and, in most cases, do not work at all.
This software may require activation (i.e. purchase) to perform its functions, yet even after activation, it remains nonoperational. Fake anti-virus tools are a prime example of PUAs that generate profit in this deceptive manner. As mentioned, these unwanted apps can have dangerous capabilities, which can lead to serious problems.
Some PUAs can force-open dubious and malicious websites. Adware-types run intrusive advertisement campaigns (i.e. deliver pop-ups, banners, coupons and others). The delivered ads diminish the browsing experience and, when clicked, redirect to dangerous sites and even stealthily download/install rogue software.
Other PUAs called browser hijackers make modifications to browser settings and restrict access to them to promote bogus search engines. The promoted search engines are usually unable to provide unique results, and so they tend to redirect to Google, Yahoo, Bing and other genuine sites.
Furthermore, most PUAs (regardless of type) can track data. They can monitor browsing activity (browsing and search engine histories) and collect sensitive information derived from it (IP addresses, geolocations and other details). The gathered data is likely to contain personally identifiable information.
PUA developers monetize this information by sharing it with and/or selling it to third parties (potentially, cyber criminals). In summary, the presence of unwanted software on devices can lead to system infections, financial loss, serious privacy issues and identity theft.
To ensure device and user safety, all suspicious applications and browser extensions/plug-ins must be removed immediately upon detection.

Registry Life, ScanUtilities and System Care Pro are some examples of other PUAs similar to Registry Cleaner. Despite how legitimate and useful this software may seem, it is usually nonfunctional and can have harmful capabilities. The only purpose of these unwanted applications is the generate revenue for the developers.
Rather than delivering any real value, PUAs cause redirects, run intrusive ad campaigns, hijack browsers and collect private data.
How did potentially unwanted applications install on my computer?
Some PUAs (including Registry Cleaner) have "official" promotional web pages, from which they can be downloaded. These apps can also be downloaded/installed with other programs. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is termed "bundling".
By rushing through download/installation processes (e.g. ignoring terms, skipping steps, using "Easy/Express" setting, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate these applications as well. When clicked, they can execute scripts to download/install PUAs without users' consent.
How to avoid installation of potentially unwanted applications
You are strongly advised to research all software products to verify their legitimacy, prior to download/installation and/or purchase.
All downloads must be done from official and verified sources, since untrusted download channels including unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders can offer deceptive and bundled content.
When downloading/installing, read the terms, explore all available options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features and other additions. It is also important to exercise caution when browsing. Intrusive ads may seem legitimate, however, they can redirect to dubious sites (e.g. gambling, pornography, adult-dating, etc.).
If you encounter ads or redirects of this kind, inspect your devices and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
