What is PCRepairClinic?
PCRepairClinic is a piece of untrustworthy software, promoted as a tool capable of cleaning and optimizing systems, by fixing and removing various errors. However, dubious techniques are used to distribute this application, hence most users download/install it unintentionally.
Due to this, it is classified as a PUA (Potentially Unwanted Application). Software within this classification often pose a threat to device integrity and/or user privacy.
While questionable proliferation methods are employed to distribute legitimate products, they are more commonly used to spread unreliable and possibly dangerous software. PUAs appear ordinary and harmless. Additionally, they tend to offer various "useful" and "advantageous" functionalities.
However, these functions rarely work as promised and in most cases - they do not work at all. Some unwanted applications (e.g. fake anti-virus tools) require activation (i.e. purchase) to perform the advertised features, yet following activation - they remain nonoperational.
Furthermore, PUAs can have unmentioned, heinous abilities. These apps can force-open untrustworthy and malicious websites. Adware-types run intrusive advertisement campaigns, i.e. deliver pop-ups, banners, coupons, surveys and other intrusive ads. Once clicked on, the delivered adverts redirect to similarly harmful sites and some can even stealthily download/install software.
Browser hijacker type PUAs modify browser settings and restrict/deny access to them - in order to promote fake search engines. The promoted web searchers are seldom capable of providing search results, so they tend to redirect to Google, Yahoo, Bing and other legitimate search engines. What is more, most PUAs (regardless of type) can track data.
They can monitor browsing activity (visited URLs, viewed pages, searched queries, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). The collected data is then monetized by being shared with and/or sold to third parties (potentially, cyber criminals).
In summary, presence of unwanted software on devices can result in system infections, serious privacy issues, financial losses and even identity theft. To ensure device integrity and user safety, all suspect applications and browser extensions/plug-ins must be removed without delay.

PC Gold Optimizer and system repair, ID SafeXpress, Web Companion, CleanMyPC and Perfect Optimizer are some examples of other PUAs similar to PCRepairClinic. Despite their legitimate appearance and broad range of functionalities, they are typically nonfunctional and can pose a threat to device/user safety.
Functionality, user convenience and safety are irrelevant - since the only purpose of unwanted software is to 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?
Select PUAs (e.g. PCRepairClinic) have "official" promotional webpages, from which they can be downloaded. They can also be downloaded/installed together with other software. This false marketing technique of packing regular programs with unwanted or malicious additions - is termed "bundling".
Rushed download/installation processes (e.g. ignored terms, skipped steps, used "Easy/Express" settings, etc.) increase the risk of unintentionally allowing bundled content. Intrusive advertisements proliferate PUAs as well. Upon being clicked, the ads can execute scripts to download/install these applications without user consent.
How to avoid installation of potentially unwanted applications?
It is important to research software before 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 sites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer harmful and/or bundled content.
When downloading/installing, it is recommended to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, features, etc. Intrusive adverts appear legitimate, however they redirect to dubious websites (e.g. pornography, gambling, adult-dating, and so forth).
Should users experience such ads and/or redirects, they must inspect their devices and immediately remove all suspicious applications and browser extensions/plug-ins detected. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
