Deleting processes

Tech-Archive recommends: Fix windows errors by optimizing your registry

I hope I am in the correct group. My computer is running slow and I went to
the task manager and a lot of processes are there and not doing anything.
There are some processes called "lucallbackproxy" using all of my memory. I
stop the process, however when I start the computer back it comes back on the
list. Is there a way to clean up the processes? I know it is probably a
basic question, but I am not very computer savy. Please be nice.
Thank you in advance,
JBG
