Registry Cleaner removal instructions
What is the Registry Cleaner PUA?
Registry Cleaner is a piece of untrustworthy software, endorsed as a tool for cleaning, repairing and optimizing the operating system - by managing registry files. However, due to the questionable methods used to distribute Registry Cleaner, it is classified as a PUA (Potentially Unwanted Application). It is noteworthy that PUAs are often unable to operate as advertised and they may even have unmentioned, harmful abilities.
Dubious distribution techniques can be used to promote legitimate software, yet such tactics are more commonly employed to proliferate unwanted and even malicious programs. PUAs typically appear ordinary and innocuous. These applications can also offer a wide variety of "useful" and "advantageous" functionalities. However, the features rarely work as promised and in most cases they do not work at all. This software may require to be activated (i.e. purchased) 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 in the introduction, unwanted apps can have heinous abilities, which may cause serious problems. Some PUAs can force-open various unreliable and malicious websites. Adware-types run intrusive advertisement campaigns (i.e. deliver pop-ups, banners, coupons and other ads). The delivered adverts diminish the browsing quality and when they are clicked on - redirect to dangerous sites and can even stealthily download/install software. Another type of PUAs called browser hijackers - make modifications to browser settings and restrict access to them in order to promote illegitimate search engines. The promoted search engines are usually unable to provide search results, so they tend to redirect to Google, Yahoo, Bing and other genuine ones. What is more, most PUAs (regardless of type) can track data. They can monitor browsing activity (browsing and search engine histories) and collect sensitive information inferred from it (IP addresses, geolocations and other details). The gathered data is highly 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, presence of unwanted software on devices can lead to system infections, financial losses, severe 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 a few examples of other PUAs akin to Registry Cleaner. Despite how legitimate and handy this software may look - it is usually nonfunctional and can have harmful abilities. Functionality and user safety are irrelevant, since the only purpose of unwanted applications is the generate revenue for the developers. Therefore, instead of delivering on any promises, PUAs can cause redirects, run intrusive advert campaigns, hijack browsers and collect private data.
How did potentially unwanted applications install on my computer?
Some PUAs (e.g. Registry Cleaner) have "official" promotional webpages, from which they can be downloaded. These apps can also be downloaded/installed together with other programs. This false marketing technique of pre-packing regular software with unwanted or malicious additions - is termed "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipping steps, using "Easy/Express" setting, etc.) - users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate such applications as well. Once clicked on, the ads can execute scripts to download/install PUAs without user consent.
How to avoid installation of potentially unwanted applications?
It is highly recommended to research software products to verify their legitimacy, prior to download/installation and/or purchase. All downloads must be done from official and verified sources. Since untrustworthy download channels, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - often offer deceptive and/or bundled content. When downloading/installing, it is advised to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features and other additions. It is just as important to exercise caution when browsing. Intrusive adverts appear legitimate, however they redirect to questionable sites (e.g. gambling, pornography, adult-dating, etc.). In case of encounters with ads and/or redirects of this kind, users must inspect their 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 Malwarebytes for Windows to automatically eliminate them.
