was using 50% of four of my processors. pretty sure it's trash. uninstalled all my logitech and I suddenly have 400MB more RAM and am using 2% of each of four cores instead of 50%. Trash software
Using 66% of a quad core processor when simply in normal use!!!! Wrong crap this is!
Causes Avast Google Chrome problem.In conjunction with Avast it appears to block access to web when using Google Chrome. Took ages to find out what was causing it. Stopping this process corrected the problem
Causes a LOT of troubles.
All I know is that after I installed my web cam and the software I downloaded for it, I started having problems. It seemed to interfere with an application that reads ane writes a lot of files. After a while the lvprcsrv.exe task was using all the cpu. I couldn't even get the cursor to move. So after a reboot, and reading about lvprcsrv.exe, I renamed the file and haven't seen the problem since. And my web cam still works.
Installed with Logitech QuickCam Drivers/Software - Safe

Seems to access memory space of other applications
To prevent this from running at startup on XP Pro, I went into Control Panel\Administrative Tools\Services, found the entry for Process Monitor (with the ominous sounding description of Injector service) and set it to Disabled. The other associated Logitech services I had were named LVCOMSer and LVSrvLauncher, which I've also disabled as I no longer use the Webcam.

Best practices for resolving LVPrcSrv issues

A clean and tidy computer is the key requirement for avoiding problems with LVPrcSrv. 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.

To help you analyze the LVPrcSrv.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
