DiskFixer removal instructions
What is DiskFixer?
DiskFixer software is endorsed as a tool for system optimization. It is allegedly capable of running various detection and removal processes, which supposedly enhance system performance. This program has a promotional website from which a free trial version can be downloaded and the full version purchased, however, DiskFixer also proliferates in other dubious ways. Therefore, it is classed as a Potentially Unwanted Application (PUA).
All software classified as PUAs is untrusted. You are strongly advised against downloading/installing and/or purchasing this software. PUAs such as DiskFixer usually require activation to perform their advertised functions. I.e., users need to purchase them. Despite any purchases made, however, they remain nonoperational. Furthermore, their download/install set-ups frequently contain more than one PUA (e.g. browser hijackers or adware). While fake system cleaners/optimizers extort money from people, unwanted applications can also possess dangerous capabilities. Some PUAs can cause unwanted redirects to sale-oriented, untrustworthy, compromised, deceptive/scam and malicious sites. Others can run intrusive advertisement campaigns (i.e., deliver pop-ups, banners, surveys, coupons and so on). The delivered ads significantly diminish the browsing experience, generate redirects to harmful web pages and stealthily download/install unwanted content (including PUAs). Another type of PUA can make unauthorized changes to browsers and limit/deny access to settings. All types have data tracking capabilities. They monitor browsing activity (browsing and search engine histories) and collect users' personal information (IP addresses, geolocations and other details). This private data can then be shared with third parties (potentially, cyber criminals) intent on misusing it for profit. To summarize, unwanted apps can cause various browser and system infiltration/infections and lead to financial loss, serious privacy issues and even identity theft. Therefore, you are advised to remove all suspect applications and browser extensions/plug-ins immediately upon detection.

OneSafe PC Cleaner, The PC Power, and Full System Care are examples of other PUAs similar to DiskFixer. These often seem legitimate and normal. They entice users to install with a wide array of "useful" functions, however, the advertised features rarely work as promised and, in most cases, are nonoperational. The only purpose of this unwanted content is to generate revenue for the developers and is not designed with user convenience in mind. Rather than delivering any real value, PUAs force-open untrustworthy/malicious pages, run intrusive ad campaigns, hijack browsers and gather vulnerable data.
How did potentially unwanted applications install on my computer?
DiskFixer can be downloaded from its official download web page. Yet, promotional sites are not the only way that PUAs proliferate. They can also be downloaded/installed together with other content. "Bundling" is the term used to describe this deceptive marketing tactic of pre-packing regular programs with unwanted or malicious additions. Rushing download/installation processes (e.g. ignoring terms, skipping steps, using pre-set options) increases the risk of unintentionally allowing bundled content onto systems. When clicked, intrusive ads can execute scripts designed to download/install PUAs without users' consent.
How to avoid installation of potentially unwanted applications
Research all content to verify its legitimacy, prior to downloading/installing. Use only trustworthy and verified download channels. Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting websites, third party downloaders and similar sources are untrustworthy and should be avoided. Untrusted download channels are far more likely to offer deceptive and/or bundled software. When downloading/installing, read the terms, study all available options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features and so on. Intrusive ads typically seem normal and harmless, however, once clicked, they can redirect to dubious pages (e.g. pornography, adult-dating, gambling and others). If you encounter these advertisements/redirects, inspect the device and immediately remove all dubious applications and/or 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.
