False Positives Report for NodeJS

When starting a http server and launching the broswer using NodeJS (node.exe), Avast Free Antivirus will report idp.helu.pse46 and prompt me powershell.exe is infected.
But when I cancel the auto launch of the broswer and start a http server only, Avast Free Antivirus will NOT report any virus behabiours anymore.

Hello, it could be a false positive. If you want a faster response from Avast, go to this page and tell us what the problem is.
