It's sensible to me that in the background the process "GV250.exe" is constantly running. But also I've noticed there're three other processes that go with it (as highlighted in yellow in attached image) - "BcastTcp.exe", "DMMailServer.exe", and "DmHealthSvr.exe". I might not be 100% correct but it seems to me that these processes are not necessary and I could terminate them anytime (though they do come back again automatically soon after).
Could anyone tell me whether they're necessary to be running all the time? If not, how can I get rid of them?
Also, I heard that the process "pctspk.exe" (highlighted in blue) is not important either. Is it correct? How do I get rid of it if it's true.
