How to uninstall the Fast! program from the operating system
Written by Tomas Meskauskas on (updated)
What kind of application is Fast!?
Fast! supposedly allows computers to run faster by speeding up applications, improving CPU execution and lowering data transmission latency, however, developers use dubious methods for distribution and thus users often install Fast! onto their computers inadvertently. Therefore, Fast! is categorized as potentially unwanted application (PUA).
Fast! application overview
The free version of Fast! allows users to run a scan designed to evaluate computer hardware and ascertain which actions can be taken to make the system run faster. In fact, users of the free version cannot take any further actions to improve computer performance without having to activate this program through making payment.
PUAs often run fake scans and do not fix any errors, remove viruses, clean unnecessary, unwanted files, etc. Commonly, they generate fake results to trick users into believing that they can improve computer performance (and provide other useful functions) by paying for software activation/registration.
It is unknown whether Fast! is one of these rogue programs, however, there is a strong possibility. Furthermore, installers for PUAs are often used to promote various browser hijackers, adware-type apps (and others of this kind). Browser hijacking apps promote fake search engine addresses by changing browsers settings.
Adware-type apps often serve ads that, when clicked, open dubious pages or even cause unwanted downloads and installations by running certain scripts. Note that adware-type apps and browser hijackers can gather browsing-related information.
In some cases, they target private, sensitive details as well. Developers sell the data to third parties (potentially, cyber criminals) or misuse it in other ways. Therefore, apps of this type should never be downloaded or installed.

Potentially unwanted application examples
More examples of programs that are categorized as PUAs include PC SmartCare, PCMate Free Driver Backup and SuperEasy Registry Cleaner. Some PUAs are legitimate, however, many are useless. They generally do not function as promised by the developers and are designed only to trick users into paying for activation/registration.
Some examples how users download and install PUAs are described below.
How did potentially unwanted applications install on my computer?
PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".
By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well.
When clicked, the ads can execute scripts to download/install these applications without users' permission. Some PUAs have "official" download web pages from which they can be downloaded.
How to avoid installation of potentially unwanted applications
You are advised to download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.
Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations.
Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
