What is DiskFixer?

DiskFixer is a piece of software, endorsed as a tool for system optimization. It is allegedly capable of running various detection and removal processes, which are supposed to 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 ways, which are dubious. Due to this, it is considered to be a PUA (Potentially Unwanted Application).

DiskFixer unwanted application

All software classified as PUAs is deemed to be untrustworthy. It is strongly advised against downloading/installing and/or purchasing such. PUAs like DiskFixer usually require activation to perform their advertised functions. In other words, users need to buy them - for the programs to work. However, often despite being purchased - they remain nonoperational. Furthermore, their download/install setups frequently contain more than one PUA (e.g. browser hijackers or adware). While fake system cleaners/optimizers are designed to scam users out of their money, unwanted applications can posses dangerous abilities as well. To elaborate, some PUAs can cause undesirable 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 seriously diminish browsing quality, generate redirects to harmful webpages and can stealthily download/install content (e.g. various PUAs). Yet another type of PUA can make unauthorized changes to browsers and limit/deny access to their settings. It is not uncommon for all types to have data tracking abilities. They monitor browsing activity (browsing and search engine histories) and collect users' personal information (IP addresses, geolocations and real-life 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 not only cause a variety of browser and system infiltrations/infections, but also as lead to financial losses, severe privacy issues and even identity theft. Therefore, it is recommended to remove all suspect applications and browser extensions/plug-ins immediately upon detection.

OneSafe PC CleanerThe PC PowerFull System Care are a few other PUAs similar to DiskFixer. These apps rarely look suspicious, they appear legitimate and ordinary. They entice users into installation with a wide array of "useful" and "advantageous" functions. However, the advertised features rarely work as promised and in most cases - they are utterly nonoperational. Functionality is irrelevant, when the only purpose of all unwanted content is to generate revenue for its developers. It is not designed with user convenience in mind and has no true value to them. Instead of delivering on any promises, 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 form its official download webpage. Promotional sites are not the only way that PUAs spread. They can also be downloaded/installed alongside other content. "Bundling" is the term used to describe this deceptive marketing tactic of pre-packing regular programs with unwanted or malicious additions. Rushed download/installation processes (e.g. ignored terms, skipped steps and sections, used pre-set options) - increase the risk of unintentionally allowing bundled content onto systems. When clicked on, intrusive adverts cam execute scripts, designed to download/install PUAs without user consent.

How to avoid installation of potentially unwanted applications?

It is highly recommended to always research content to verify its legitimacy, prior to downloading/installing it. Only trustworthy and verified download channels should be used. Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting websites, third party downloaders and similar sources are considered to be untrustworthy; therefore, they are advised against use. Unreliable download channels are far more likely to offer deceptive and/or bundled software. When downloading/installing, users are urged to read terms, study all available options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features and so on. Intrusive ads typically appear ordinary and harmless, however once they are clicked - they redirect to questionable pages (e.g. pornography, adult-dating, gambling and others). In case of encounters with such advertisements/redirects, users are advised to 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 Spyhunter for Windows to automatically eliminate them.
