Just had a pop-up saying this background program has just finished installing. I've no idea what it is, where it came from, or how to get rid of it; there's nothing in Add/Remove Programs etc. Any ideas?
if you have killer ethernet card or killer wifi then killer command center is a software that manages them. i recommend that you remove it because it messes things up and causes bsod and you have to follow a driver only approach for ethernet card and wifi. https://support.killernetworking.com/knowledge-base/how-do-i-remove-the-killer-control-center/ tells u how to remove killer command center
