Hi, I do not really know what happened. Shortly after the update of the virus database around 12.10 am, my whole computer started to freak out, hang, screen went striped and I tried to restart it. It did not start. I tried again and again. After 3rd trial it finally started. Some blue bios or dos (dont know as Im not profi) screen came up. All was just freaky. Finally it started properly, but the nightmare with Win32:Delf-MZG flags started. Once I got the VPS - 091203-1 the false positive issue stopped, but computer still does not start properly. Looks like something deeply damaged, in registry, system files. I did nothing - it was just avast update !!! Can not explain it better - as I said Im not a profi, but I know computers enough to say that this misery with my system is the fauls of Win32:Delf-MZG false positive from avast. What shall I do with my system now, so it comes back to normal functioning?
