This file is the image caching service for RamSoft PowerReader. It is not malware or spywhere as it is only installed after user consent and it is for the reading of Radiology Exams

I found it located in C\ProgramFiles\RamSoft\PowerReader4 folder; this is a product that is used to view medical images from a cd (x-rays, etc...)(it is usually loaded onto the cd when they burn it for you at the clinical site; it auto runs when you load the cd). I found one named PRCacheService.exe, & one named prcacheservice.exe; but in separate subfolders; I think the lowercase one may be malware--it often eats up lots of memory on my laptop & I have to open up resource monitor to end the process tree

Best practices for resolving prcacheservice issues

A clean and tidy computer is the key requirement for avoiding problems with prcacheservice. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
