Is this malware or something ?

I’ve just gotten a pc and I’m not very good with them, this randomly popped up after playing l4d last night, someone joined my friends only game using my exact account name and was even playing the same character as me, within the same game, I’m worried it’s some kind of virus, my antivirus doesn’t pick it up and neither does windows defender, any ideas? When I right click and do a web search on it, it pretty much comes up with pages indicating it to be malware, if it is, how tf do I remove it ? It doesn’t have a file location either so all I’ve been able to do really is disable it (the top 2)
