Hi,
I just re-installed Avast! Home Edition. Now I scheduled a bootscan and it comes up with a few errors (see subject). No other information is given. What does this error mean?
Have a look HERE and follow the links technical posted. Are they of any help to you?
error 3221225506 - is Access Denied. Try modifying security properties of the file to allow full control to everyone and then running the boot time scan again.
