PC CURE PRO removal instructions

What is PC CURE PRO?

PC CURE PRO is the name of an untrustworthy application, promoted as an operating system optimizing tool. It is supposedly capable of resolving Windows Registry issues and removing various errors. Due to the dubious techniques used to distribute this app, it is categorized as a PUA (Potentially Unwanted Application). Software within this category tends to appear legitimate, yet it is usually nonoperational. Furthermore, PUAs often have unmentioned, heinous abilities.

Questionable distribution methods may be used to promote legitimate products, but they are more commonly employed to proliferate unreliable and even malicious software. PUAs typically look ordinary and "useful". However, these apps rarely work as advertised, and in most cases - they are utterly non-functional. Fake anti-viruses are prime examples of this type of PUAs. This software requires activation (i.e., purchase) to perform the features, yet following activation - they remain nonoperational.

As mentioned in the introduction, PUAs can have harmful functionalities, and these functions can be in different combinations. Some unwanted applications can force-open untrustworthy, misleading, deceptive/scam, and malicious sites. Adware-types run intrusive advertisement campaigns (i.e., deliver various ads). The delivered adverts diminish the browsing experience and are deemed to be dangerous. Once clicked on, the advertisements redirect to dubious/malicious webpages, and some can stealthily download/install software (e.g., PUAs). Browser hijackers are another type of PUAs; they operate by making changes to browser settings and restricting/denying access to them - in order to promote fake search engines. The promoted web searchers seldom can provide search results, so they redirect to Google, Bing, Yahoo, and other legitimate search engines.

Most PUAs (regardless of type) have data tracking abilities. Information of interest includes: browsing and search engine histories, IP (Internet Protocol) addresses, geolocations, and personally identifiable details. PUA developers monetize the collected data by sharing it with and/or selling it to third-parties (potentially, cyber criminals). In summary, presence of unwanted apps on devices - can result in system infections, severe privacy issues, financial losses, and even identity theft. To ensure device integrity and user privacy, all suspicious applications and browser extensions/plug-ins must be removed immediately upon detection.

PC Optimizer ProPC Accelerate, and Registry Medic are a few examples of unwanted applications similar to PC CURE PRO. PUAs entice users into download/installation and/or purchase with a broad range of "handy" features. The promised functionalities range from system cleaning/optimization to specific online content easy access tools. Despite how good the functions may sound, they usually do not work. This software's sole purpose is to generate profit for the developers; hence, functionality and user safety are irrelevant. Therefore, instead of delivering on any promises, PUAs can cause redirects, run intrusive advert campaigns, hijack browsers, and collect sensitive and private information.

How did potentially unwanted applications install on my computer?

Some PUAs (e.g., PC CURE PRO) have "official" promotional/download sites. These applications can also be downloaded/installed together with other programs. This false marketing tactic of pre-packing regular software with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g., ignored terms, skipped steps and sections, etc.) increase the risk of unintentionally allowing bundled content into the system. Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to make downloads/installations without user permission.

How to avoid installation of potentially unwanted applications?

It is recommended to research software products before download/installation and/or purchase. Additionally, all downloads must be done from official and verified sources. Untrustworthy download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - can offer bundled content. When downloading/installing, it is advised to read terms, study possible options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features, etc. Intrusive adverts appear legitimate and harmless; however, they redirect to highly questionable webpages (e.g., gambling, pornography, adult-dating, and so forth). In case of encounters with such ads and/or redirects, the system must be inspected and all suspect applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
