What is McCSPServiceHost.exe?

The genuine McCSPServiceHost.exe file is a software component of McAfee Cloud Services Platform by McAfee LLC.
"McCSPServiceHost.exe" and four associated ".DLL" files, (full path: "C:\Program Files\Common Files\McAfee\CSP\%VERSION#%\McCSPServiceHost.exe"), provide a computer's connection to McAfee's Cloud Services Platform, (CSP), which enables multiple McAfee services and products to benefit from their Global Threat Intelligence (GTI) where they continually amass information from all of their customers about cybersecurity threats and site reputations. It is also involved in detecting and applying automatic updates of the McAfee scanning engine and synchronizing subscription details across multiple devices, (desktop and mobile), on a network. CSP first appeared in June 2015 as part of updates to Web Advisor and other McAfee products and services and some McAfee forum moderators had to ask what it was. John McAfee founded McAfee Associates in 1987, now the world's largest dedicated security technology company as McAfee LLC. After several years (2011-2017) as Intel Security, it is now again a standalone company. Intel still owns 49%.
