Abrasive unwanted application removal instructions
What is the Abrasive PUA?
Abrasive is a piece of software, endorsed as a tool for running operating system diagnostics and fixing various issues. It is supposedly capable of improving device operation speed and removing registry errors. Due to the dubious methods used to distribute it, the Abrasive app is considered to be a PUA (Potentially Unwanted Application).
Questionable distribution techniques are not uncommon for ordinary and operational software, however they are mostly used to proliferate untrustworthy content. Despite their legitimate appearance, PUAs are seldom operational. To elaborate, certain PUAs (e.g. fake anti-virus and system optimization tools) require activation (i.e. purchase) to perform their advertised functionalities. However, even after being purchased - this software usually remains nonoperational. Additionally, PUAs can have heinous abilities. They can force-open sale-based/promotional, rogue, deceptive/scam, compromised and malicious sites. Adware-type unwanted apps run intrusive advertisement campaigns. This kind enables the placement of pop-ups, banners, coupons and other intrusive adverts on any visited webpage. The ads diminish the browsing experience and once clicked on - redirect to unreliable/malicious websites and some can stealthily download/install software. Another type called browser hijackers modify browser settings in order to promote fake search engines. The promoted web searchers are seldom capable of providing search results, so they redirect to Google, Yahoo, Bing and other genuine search engines. What is more, most PUAs (regardless of type) have data tracking abilities. Typically, these applications monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). The gathered data is highly likely to contain personally identifiable information and PUA developers monetize it by sharing it with and/or selling it to third parties (potentially cyber criminals). To summarize, presence of unwanted apps on devices can result in system infections, financial losses, serious privacy issues and even identity theft. To protect device integrity and user safety, all suspect applications and browser extensions/plug-ins must be eliminated immediately upon detection.

System Care Pro, Perfect Optimizer, RocketFixio and PC Win Booster are a few examples of PUAs similar to Abrasive. Users are enticed into download/installation with offers of a wide variety of "useful" functionalities; ranging from system cleaning/optimization to easy access tools. However, the promised features are seldom operational. The sole purpose of unwanted applications is to generate profit for the developers; to users - they have no real value and can instead cause various issues. PUAs are designed to run intrusive advert campaigns, cause redirects, hijack browsers and collect private data.
How did potentially unwanted applications install on my computer?
Select PUAs (e.g. Abrasive) have "official" promotional pages, from which they can be downloaded. However, they are more commonly downloaded/installed alongside other products. This deceptive marketing technique of pre-packing ordinary software with unwanted or malicious additions - is termed "bundling". Rushed downloads/installations (e.g. ignored terms, used pre-set options, etc.) - increase the risk of unintentionally allowing bundled content into the system. Intrusive ads proliferate these apps as well. Once clicked on, they can execute scripts to download/install PUAs without user consent.
How to avoid installation of potentially unwanted applications?
All products must be researched prior to download/installation and/or purchase. It is recommended to only download from official and verified sources. Untrustworthy 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 important to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, features, etc. Intrusive advertisements appear legitimate, however they redirect to various questionable webpages (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with adverts/redirects of this kind, the system must be inspected and all suspicious applications and/or browser extensions/plug-ins immediately removed from it. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
