Okay about one hour ago i got an email from the virus labs and was asked to update the virus definitions to version 110602-1 and then rescan my computer…the result:

* avast! Report * This file is automatically produced * * Task 'Full system scan "used * Created on Thursday, June 2, 2011 4:27:29 p.m. * VPS: 110602-1, 06/02/2011 *

Infected files: 0

  • Task stopped: Thursday, June 2, 2011 5:19:32 p.m.
  • Run-time was 52 minute (s), 3 second (s)

So in my case the problem is solved. And like the previous time they reacted quickly in my opinion, thank you Avast virus labs. ;D
