Thanks very much for your help!

I got the error msg just before the scan and then it just went on scanning like nothing was wrong.

I followed the instructions on the thread you gave me igor.
The value of “BootExecute” included:

C:\Program\ALWILS~1\Avast4\aswBoot.exe /A:“" /L:“English”
C:\Program\ALWILS~1\Avast4\aswBoot.exe /A:"
” /L:“English”
C:\Program\ALWILS~1\Avast4\aswBoot.exe /A:“*” /L:“English”

By removing these lines the problem was fixed! Not sure though why there were three lines…

Thanks again! :smiley:
