What is Run Speed Check?
The Run Speed Check browser hijacker operates by modifying browser settings to promote feed.runspeedcheck.com, a fake search engine.
Furthermore, it has data tracking capabilities that are employed to monitor users' browsing activity. Due to the dubious methods used to distribute Run Speed Check (most users install it unintentionally), it is also classed as a Potentially Unwanted Application (PUA).
Browser hijackers primarily target Google Chrome, Internet Explorer, Mozilla Firefox and other popular browsers with large user bases. After successful infiltration, the hijackers reassign the homepage, default search engine and new tab/window URL to the addresses of their bogus search engines.
Run Speed Check promotes feed.runspeedcheck.com in this manner. These changes may sound minor, however, they diminish the browsing experience. To elaborate on how this affects browsers, each search query typed into the URL bar and each new tab/window opened redirects to feed.runspeedcheck.com.
Fake search engines are usually unable to provide unique results and so redirect to (or cause redirection chains ending with) a legitimate website. This is the case with feed.runspeedcheck.com, which redirects to search.yahoo.com (a genuine search engine).
Furthermore, these changes are not easy to undo. With the browser hijacker still present, any changes users attempt to make to their browsers are automatically reset, if indeed access to settings is allowed at all. Therefore, to recover the hijacked browser, it is necessary to remove the rogue software responsible.
Note that Run Speed Check has data tracking capabilities - it records users' browsing habits (URLs visited, pages viewed and search queries typed, etc.) and personal information (IP addresses, geolocations and other details). This sensitive data is often shared with third parties (potentially, cyber criminals) intent on misusing it for financial gain.
The presence of data-tracking content on systems can cause various infiltration and infections, lead to serious privacy issues, financial loss and identity theft. To ensure device and user safety, remove all suspect applications and browser extensions/plug-ins from systems without delay.

PUAs often seem legitimate and entice users into download/installation with offers of "useful" features. These functions rarely work and are often nonoperational. The only purpose of PUAs is to generate revenue for the developers at users' expense. They cause serious problems and regular users receive no value.
PUAs modify browsers, force-open untrusted and malicious sites, deliver intrusive ads (e.g. pop-ups, banners, surveys, etc.) and collect private data.
How did Run Speed Check install on my computer?
PUAs proliferate through download/installation set-ups. This deceptive marketing tactic of packing regular content with unwanted or malicious software is called "bundling".
When downloading/installing, ignoring terms, skipping steps and sections, using pre-set options increases the risk of unintentionally allowing bundled programs onto systems, thereby endangering them with potential infiltration and infections. Some of these applications have "official" download web pages. Intrusive advertisements also proliferate unwanted apps.
Once clicked, they can execute scripts to stealthily download/install PUAs.
How to avoid installation of potentially unwanted applications
You are advised to research all content, prior to download/installation. All downloads should be performed via official and verified sources. Untrustworthy download channels such as Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule, etc.), free file-hosting websites and other third party downloaders can offer deceptive and/or bundled software.
Approach download and installation processes with care. Read the terms, study all possible options, use the "Custom/Advanced" settings to opt-out of supplementary apps, tools, features and so on. Intrusive ads often seem normal and innocuous, however, they cause redirects to dubious pages (e.g. pornography, adult-dating, gambling and others).
If you encounter these ads/redirects, inspect the device and immediately remove all suspicious applications and/or browser extensions/plug-ins. If your computer is already infected with Run Speed Check, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
