Recently I have been getting a message in Chrome stating “virus scan failed” when I try and download anything. Pretty sure Avast is the culprit as it doesn’t happen if I disable it.

I have also found that recently I have been getting false positives for Powershell.exe
avast blocked powershell threat idp.helu.pse71 command line detection? This particular error appears to have coincided with an install of JetBrains IDEs.
Anyone have any ideas?
