CrowdCores removal instructions

What is CrowdCores?

CrowdCores is a potentially unwanted program created by Flexagrid Systems Ltd. Developers of this software claim that it enables computers to connect across the world to solve complex computing problems. While this functionality does not appear to be malicious, be aware that CrowdCores is categorized as adware, and moreover, some trusted antivirus programs categorize this program as a Trojan (this could be a false positive). This software should not be trusted, since its functionality is identical to a brand of malware that transforms PCs into bitcoin miners and drains computer resources without the user's consent.

crowdcores adware

At time of research, we found no issues with CrowdCores regarding privacy or unwanted ads, and this program does not track users' Internet browsing activity or generate online advertisements. Commonly, Internet users often install this potentially unwanted program without their consent when downloading or installing free software. Developers of this program use a deceptive software marketing method called 'bundling'. At time of testing, CrowdCores was distributed using fake video player downloads and fake browser updates. CrowdCores adds no value for computer users, and therefore, you are advised to eliminate this adware from your operating system.

CrowdCores is similar to other adware, which infiltrates users' computers via free software downloads. Examples include, PC Data App, M6 Processing, and GigaClicks Crawler. To avoid installation of potentially unwanted applications such as these, be attentive when downloading and installing free software. Today, most freeware download websites (including download.com, softonic.com, and many others) employ 'download clients' - small programs, which manage the download process of chosen free programs and monetize these websites' free services by offering installation of advertised applications. To avoid adware infections, decline installation of any advertised programs, and when installing downloaded free programs, choose the 'Advanced' or 'Custom' installation options - this will reveal any bundled adware listed for installation. Computer users who have already installed CrowdCores, should use this removal guide to eliminate it from their operating system.
