After boot scan i coudn’t start my windows. I ahve to reinstall windows.
Where is log from boot scan?
Difficult to find if you have to reinstall …
If you haven’t done the deed yet:
Look in the C:\Documents and Settings\All Users\Application Data\Avast Software\Avast\report\aswBoot.txt file (XP location)
C:\ProgramData\Avast Software\Avast\report\aswBoot.txt (Vista, Win7 or later OS location), check this file using notepad for info on the scan/detections, etc.
What options did you use for anything Avast may have found ???
