OneSafe PC Cleaner removal instructions
What is OneSafe PC Cleaner?
OneSafe PC Cleaner is a piece of software, considered to be a PUA (Potentially Unwanted Application). It is endorsed as system cleaning tool, capable of scanning and removing various threats and issues. One of this application's proliferation methods is via deceptive/scam websites, which is why it is classified as a PUA. Users should note that unwanted apps can also be inadvertently downloaded/installed alongside other programs (often when downloaded from untrustworthy sources).
PUAs are highly unreliable and potentially harmful applications. Any content categorized as such is advised against installation. Typically (despite being advertised as free), PUAs like OneSafe PC Cleaner require activation to become operational, i.e. they need to be purchased to work. However, even after being activated - they tend to remain nonoperational. It is not uncommon for download/install setups used to spread these apps to contain more than one PUA (e.g. adware or browser hijackers). While the sole purpose of unwanted applications is to generate revenue for their developers, they can have different methods of accomplishing this. Some types force-open sale-based, untrustworthy, compromised, deceptive/scam and malicious websites. Others can run intrusive advertisement campaigns, doing so by implementing varied tools to enable third party graphical content. Hence, the delivered ads severely diminish browsing quality (limit browsing speed and site visibility). Intrusive advertisements also carry certain risks. When clicked, they can redirect to likewise dangerous webpages and select ads can even execute scripts, designed to stealthily download/install PUAs. Yet another type of unwanted app can make unauthorized changes to browsers and limit/deny access to their settings (i.e. hijack the browsers). By far the most heinous ability, which most PUAs possess, is data tracking. They use this ability to monitor users' browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect their personal information (IP addresses, geolocations and real-life personal details). This vulnerable data can then be shared with third parties (not unlikely, cyber criminals), intent on misusing it for financial gain. To summarize, presence of PUAs on devices can cause a variety of browser/system infiltrations and infections, as well as lead to financial losses, serious privacy issues and even identity theft. To ensure device and user safety - all suspicious applications and/or browser extensions/plug-ins must be removed without delay.

Full System Care, BitSecure AV, Complete System Care are examples of software similar to OneSafe PC Cleaner. PUAs can offer a wide array of "useful" and "beneficial" functions/features, such as system cleaning/optimization, web search enhancement, quick access to specific content - to name a few. Regardless of good these offers may sound, rarely do the advertised features work, even if they do - then not as promised. Instead of delivering on any promises, PUAs generate redirects to untrustworthy/malicious pages, run intrusive advert campaigns, hijack browsers and track private data.
How did potentially unwanted applications install on my computer?
Some PUAs (e.g.) have "official" promotional webpages, which are frequently accessed through various scam sites. This proliferation method is used by OneSafe PC Cleaner. However, PUAs also proliferate via download/install setups of other software. This false marketing method of pre-packing ordinary programs with unwanted or malicious content is called "bundling". Rushed download/installation processes (e.g. ignored terms, skipped steps, used presets, etc.) - increase the risk of potential system infiltrations and infections. When clicked on, intrusive advertisements can execute scripts to download/install PUAs, without user consent.
How to avoid installation of potentially unwanted applications?
Users are advised to research content, prior to downloading/installing it. Only official and verified download channels should be used. Untrustworthy download sources like: P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting websites, third party downloaders and similar are more likely to offer deceptive and/or bundled software. When downloading/installing, it is important to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, functions and so on. Intrusive adverts commonly look legitimate and innocuous, however they redirect to unreliable and questionable pages (e.g. pornography, adult-dating, gambling and others). Should users experience such ads/redirects, it is strongly recommended to inspect the device and immediately remove all suspect applications and/or browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
