My Avast also went crazy, starting today. Kubectl was moved to quarantine on my PC as well. I wrote a forum post about it earlier today.
In addition, when I tried to download installation media for Windows 11, it said that the download site for win11 "software-static.download.prss.microsoft.com/.... " was on a blacklist??
I am reinstalling Windows even though these likely are false alarms. I'm getting nervous from all these red alert messages... It's a real bummer to loose almost a day at work due to this..
