UniBlue (formerly LIUtilities) have numerous 'packages' that are actually bundles of utilities. Processlibrary is part of some of these apps (including WinTasks). When you click on a process in WinTasks Pro (not sure about standard) it looks up the process in processlibrary (which is actually included and updated as part of the package) and displays the details within the main screen - you can expand it and view it in a larger screen and it has links to the website.
As far as I can see the website (and the info in the database) are designed to get you to download other products. Quickly skipping through a number of common processes on my computer I get very similar messages to the one I posted at the start of this thread namely (to paraphrase) "essential do not stop this process ... registered as a trojan delete it". Seems particularly to apply to MS process but not exclusively.
Maybe I should report this behaviour to MS since they proudly display the Gold Partner label on their website since they effectively seem to be arguing that almost any essential MS process in Windows is registered as a trojan.
Note they don't say 'potential target for trojans and other malware' - which would be a more reasonable approach - they actually advocate removal of core windows functions like Explorer!! Anyone using this library that isn't tech savvy is going to have a hard time understanding what is required of them - and that it is actually impossible if you want your computer to function.
LIGHT GOES ON
Ah! What they are actually saying is WinTasks as a security app recommends the removal of Windows from your system - that makes sense!
This one is even more classic:

So far all the MS processes I have looked at are labelled in similar ways ... some (like this one) even more severely than explorer.exe.
