How to uninstall the Fast Computer unwanted application
Written by Tomas Meskauskas on (updated)
What is the Fast Computer app?
Fast Computer (Ускоритель Компьютера) is a Russian application endorsed as a tool for optimization of Windows Operating Systems. According to its advertisement, it is capable of enhancing device speed up to 70% with such features as removal of junk files, start-up speed improvement, and so on.
In fact, this app is classified as a Potentially Unwanted Application (PUA) due to its dubious proliferation methods. Note that Fast Computer is often bundled with Yandex Internet browser and Yandex Toolbar. Hence, this additional software is often installed together with Fast Computer.
Software falls within the PUA classification primarily due to how it is marketed/distributed. These dubious tactics such as 'bundling' are commonly used for unwanted applications. Legitimate software may be marketed using this technique as well, however, it is more often used to promote dubious products.
PUAs are untrusted, as they are frequently nonoperational and can even have harmful capabilities. Some PUAs (e.g. fake anti-virus tools and other types) require activation to perform the advertised functions, yet after being activated (i.e. purchased) they remain nonfunctional.
As well as not working as promised, unwanted apps can have other capabilities. Adware-type PUAs deliver intrusive advertisement campaigns. They typically enable the placement of pop-ups, banners, coupons, surveys and other ads on any visited website.
This significantly diminishes the browsing experience, as the ads limit browsing speed and web page visibility. Additionally, when clicked, intrusive ads redirect to untrusted/malicious pages and stealthily download/install software. Unwanted applications can also force-open sale-oriented, rogue, compromised, deceptive/scam and malicious sites.
Another type called browser hijackers can modify browser settings and restrict/deny access to them - to promote bogus search engines. These fake search engines are usually unable to provide unique results, and so they tend to redirect to Google, Yahoo, Bing and other genuine search engines.
Furthermore, many PUAs have data tracking capabilities. They can monitor browsing activity (browsing and search engine histories) and collect sensitive data extracted from it (IP addresses, geolocations and other details). This data is highly likely to contain personally identifiable information, which PUA developers often monetize by sharing with or selling to third parties.
Therefore, the presence of unwanted apps on devices can lead to system infiltration and infections, financial loss, serious privacy issues and identity theft. To ensure device integrity and user safety, you are strongly advised to eliminate all suspicious applications and browser extensions/plug-ins immediately upon detection.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner.
WisePCDoctor, HomeGuard, DriverMax and Orange Defender Antivirus are some examples of other PUAs. These unwanted apps rarely seem suspicious and typically appear as normal and useful software.
People are often tempted into download/installation with offers of various features, ranging from system cleaning/optimization to easy access tools for online content, however, these functions seldom work as promised and, in most cases, do not work at all. The only purpose of PUAs is to generate revenue for the developers.
Regular users receive no genuine value, since PUAs do not work as promised and simply cause issues. PUAs run intrusive ad campaigns, force-open dubious websites, hijack browsers and track private data.
How did potentially unwanted applications install on my computer?
Some PUAs (including Fast Computer) have "official" promotional web pages from which they can be downloaded, however, they can be installed with other software as well. This deceptive marketing method of pre-packing regular content with unwanted or malicious additions is called "bundling".
While it is often possible to opt-out (i.e., decline download/installation) of these various additions, rushing through download/installation processes (e.g. ignoring terms, skipping steps and sections, etc.) increases the risk of missing such options.
Intrusive advertisements also proliferate these apps. Once clicked, they can execute scripts to download/install PUAs without users' permission.
How to avoid installation of potentially unwanted applications
Research all products to verify their legitimacy prior to download/installation and/or purchase. All downloads must be performed from official and verified sources. Unofficial and free file-hosting (freeware) sites, Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders are untrusted, since they can offer deceptive and/or bundled content.
When downloading/installing, you are advised to read the terms, explore all available options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, functions and other additions. It is also important to exercise caution when browsing.
Intrusive ads may seem normal and harmless, however, they often redirect to highly dubious and suspicious pages (e.g. gambling, pornography, adult-dating and others). If you encounter ads/redirects of this kind, check the system and remove any dubious applications and browser extensions/plug-ins immediately.
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
