OneLaunch redirect removal instructions
What is OneLaunch?
OneLaunch is an ad-supported browser based on a free and open-source software project from Google called Chromium. It is worthwhile to mention that OneLaunch is distributed alongside with a Games toolbar. It is common that users download and install adware-type apps like OneLaunch without knowing about it, therefore, they are categorized as potentially unwanted applications (PUAs).
Ad-supported applications (and websites) generate advertisements. Some examples of types of ads that they generate are coupons, surveys, banners, pop-up ads. It is common that their ads, if clicked, open questionable websites. Also, sometimes they cause unwanted downloads and/or installations by running certain scripts. Another problem with adware-type apps is that they can be designed to function as data collectors targeting browsing data (like IP addresses, geolocations, entered search queries, addresses of visited sites) or even sensitive, personal information. What is worse, their developers could sell collected data to third parties (potentially cyber criminals) or misuse it in other ways. It means that users who have apps like OneLaunch installed on their computers (or browsers) risk to encounter problems related to online privacy, browsing safety, or even become victims of identity theft. Therefore, such apps should never be trusted (download and installed).

It is common that applications like OneLaunch are advertised as useful, legitimate applications that supposed to improve web browsing experience, deliver some features, etc. Although, most of them are useless to their users and can be the culprit of various problems. Some examples of other adware-type apps are Valerie, WikiNow and Chromium Shield. An app that is most similar to OneLaunch is called WebDiscover.
How did adware install on my computer?
As mentioned in the first paragraph, in most cases users download and install PUAs unintentionally. Usually they cause it by clicking various unreliable, deceptive advertisements or alongside with other programs (when developers distribute them by using a "bundling" method). In the second case users cause it when they finish download and/or installation processes without declining offers to download and/or install unwanted apps. Usually it can be done via "Custom", "Advanced" and other settings of download and/or installation setups. Deceptive ads can cause unwanted downloads and installations by running certain scripts, however, they cannot do that without being clicked.
How to avoid installation of potentially unwanted applications?
It is recommended to download software only from official, trustworthy websites. Other sources (or tools) like unofficial sites, Peer-to-Peer networks (torrent clients, eMule and so on), third party downloaders, should not be used. The same applies to third party installers. Also, it important to check if download and/or installation setup has settings (like "Custom", "Advanced") before completing a download or installation process, its settings could be used to decline offers to download and/or install unwanted software. Additionally, it is advised not to click advertisements that are displayed on shady websites - they can be designed to promote potentially malicious websites or cause unwanted downloads, installations. If there are any unwanted apps (extensions, add-ons or plug-ins) installed on a browser or programs of this kind installed on the operating system, then they should be removed. If your computer is already infected with rogue applications, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
