League client is compromised

Hello, so I got virus which reopened windows powershell and used up all available cpu. So i tried to figure out the issue. After few hours i found out that it's Mimikatz and Ethernal_Blue type virus. So i tried to find out where it comes from so after few hours more I found that it comes from League Client (LC) . Only way to remove it is to reset/reinstall windows. How I determined it's from LC? Well one IT specialist recommended to run command line in windows powershell right here: https://gyazo.com/ff6b5cb451820f658fef6c435874984d which shows that it comes from LC, i also reseted windows several times and there was no problem until I installed LC. I downloaded LC from official site. Also there is a way to make it comsume less cpu by writing command line in powersell: while ($true) {Get-Process Powershell | Where-Object {$_. ID - notcontains $PID} | Stop-Process -Force} . This command line repeatedly turns of new powershell windows. Note you have to leave windows powershell open otherwise it won't work. I also submitted support ticket to Riot Games.
