Fast! removal instructions

What is Fast!?

Fast! is the name of a program which is promoted as a tool that makes a computer to run faster by speeding up applications, improving CPU execution and lowering data transmission latency. However, developers use questionable methods for its distribution which increases the chance that users who have Fast! installed on their computers did it unknowingly. Therefore, Fast! is categorized as potentially unwanted application (PUA).

Fast! unwanted application

The free version of Fast! allows users to run a scan designed to evaluate computer hardware and see what it can do to make a computer to run faster. However, users of the free version cannot take any further actions to improve computer performance without having to activate this program which is not free. The problem is that quite often apps that are categorized as PUAs run fake scans and do not fix any errors, remove viruses, clean unnecessary, unwanted files, etc. It is common that they generate fake results to trick users into thinking that they could improve computer performance or do other things by paying money for software activation/registration. It is unknown whether Fast! is one of these programs, however, there is such a possibility. Furthermore, it is common that installers for PUAs are used to promote various browser hijackers, adware-type apps (and/or other apps of this kind). Browser hijackers are apps that are designed to promote fake search engines (their addresses) by changing browsers settings. Adware-type apps can be (and often) serve various ads that, when clicked, tend to open questionable pages or even cause unwanted downloads, installations by running certain scripts. It is worthwhile to mention that both adware-type apps and browser hijackers can be designed to gather browsing-related information. In some cases they can be designed to target sensitive details as well. There is always a possibility that their developers may sell collected data to third parties (potentially cyber criminals) or misuse it in other ways. Therefore, apps of this type should not be downloaded and installed.

More examples of programs that are categorized as PUAs are PC SmartCare, PCMate Free Driver Backup and SuperEasy Registry Cleaner. There are many legitimate PUAs, although, there are many useless ones as well. The aforementioned PUAs do not function as they supposed to (as their developers promote them) and are designed only to trick users into paying money for their activation/registration. A couple of examples how users download and/or install PUAs are described in the next paragraph.

How did potentially unwanted applications install on my computer?

Sometimes users cause unwanted downloads and/or installations by clicking deceptive advertisements that are designed to execute certain script. Although, in most cases they cause them by downloading and/or installing programs without checking settings of their download and/or installation setups. It is common their "Advanced", "Custom" or other settings can be used to decline offers to download and/or install unwanted apps. When users download and/or install without changing setup's settings or unticking available checkboxes, they download and/or install included apps (PUAs) too.

How to avoid installation of potentially unwanted applications?

If a download and/or installation setup has settings like "Custom", "Advanced", they should not be left unchecked. It is common that those settings mention offers to download and/or install additional software and can be used to decline them. Programs (and files) should be downloaded from official websites and through direct links. Third party downloaders, installers, unofficial websites, Peer-to-Peer networks (e.g., torrent clients, eMule), and other similar channels, sources should not be used as tools to download and/or install any software. It is because they can be used as tools to distribute various unwanted applications. Intrusive ads that are displayed on questionable websites should not be clicked as well  - they often are designed to open untrustworthy pages or cause download and/or installation unwanted software. Any suspicious, unwanted extensions, plug-ins and/or add-ons that are installed on a browser or programs of this kind that installed on the operating system should be removed. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
