yes, it fully removed everything without problems, did a reboot before installing avast aswell.
I just noticed that it was scanning a USB drive (and that's USB 1.0 or 1.1 on that computer = slow),
so my 3 1TB usb drives are not seen as swappable media
and where included in the "All drives" option that the full scan has.
I changed this to system disk or something and restarted the scan again.
I see it's processing .txt files and other "safe" extentions although I selected scan by extension.
@Pondus: thanks for the link, I'll go through that now.
