What is RelevantKnowledge?
RelevantKnowledge is advertised as a tool that people can use to express their opinions about various products and services by participating in online research, however, this app is classified as adware and serves advertisements.
Commonly, users download and install adware inadvertently and, therefore, apps of this type are categorized as potentially unwanted applications (PUAs).
Usually, programs such as RelevantKnowledge serve surveys, banners, pop-ups, coupons and other types of advertisements. This particular app displays surveys on various shopping websites, however, it could also serve other ads.
Note that, if clicked, ads served by adware can open dubious web pages or even download and install unwanted software by executing certain scripts. Additionally, adware can record data relating to users' browsing habits. For example, IP addresses, addresses of visited websites, geolocations, entered search queries and other details of this kind.
RelevantKnowledge is likely to collect data such as products purchased from online shops as well. Furthermore, some adware can gather personal, sensitive information. The data is misused to generate revenue by selling it to third parties (potentially, cyber criminals) or in other ways.
In any case, remove programs such as RelevantKnowledge from your computers and browsers.

RelevantKnowledge is related to another program called PremierOpinion. Examples of other software that is classified as adware are WikiNow, DreamTrip and Shop Together. Generally, programs of this type are designed only to generate revenue for the developers by serving ads and collecting data. They are useless to regular users and can cause serious issues.
How did adware install on my computer?
RelevantKnowledge is promoted in the installer for PCMate Free Privacy Cleaner. This distribution method for PUAs such as RelevantKnowledge is called "bundling". In such cases, developers include potentially unwanted apps into the download/installation set-ups as 'additional offers'.
Typically, such offers can be declined (via "Custom", "Advanced" settings or by unticking checkboxes that are available in the set-ups), however, many users fail to check or change these settings, thereby downloading and installing PUAs inadvertently with their regular programs.
In some cases, users download and install PUAs through deceptive advertisements that execute certain scripts.
How to avoid installation of potentially unwanted applications
Download software and files from official websites and via direct links. It is not safe to use torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, unofficial websites or other sources of this kind. Avoid third party installers. Check "Advanced", "Custom" and other settings, and decline offers to download or install unwanted software.
Do not click ads that are displayed on dubious websites, since they can open other untrusted websites or even cause unwanted downloads and installations. Remove any unwanted, suspicious applications (extensions, add-ons, and plug-ins) that are installed on the browser.
The same should be applied to programs of this kind that are installed on the operating system. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
