In the last couple of days, I've been getting the idp.alexa.53 message repeatedly when using Visual Studio Code, when using the terminal. Avast is blocking 'powershell.exe'. I also get the message when running powershell in admin mode, or when running Windows Terminal.
I submitted powershell.exe to virustotal.com and nothing was detected. I assume Avast is issuing a false positive, but it's concerning.
Avast doesn't have a problem with git bash, so I added it as an optional terminal in VS Code. It's a workaround, but annoying.
