What avast version are you using ?

  • this was previously a problem in earlier builds.
  • however that was rectified in the latest regular release of avast 2015 10.4.2233 if memory serves me well.

That said I’m currently running a beta build 11.1.2238 of avast 2016 and the actual scan duration is much greater than has been in the past, but at least it completed (I thought it might have been stalled.

I have also run a Smart Scan (which included the scan for Network threats) and that appeared to be almost quicker than the Network scan on its own.
