Why doesn’t “Scan on Close” block the file? If a file is saved to my disk I’d like it to be block at once if avast! finds a virus in it (just to be sure). I though the “Virus Warning” dialog box (with the sound and animation) stopped ALL activity.

I have no renaming or other strange things, and this incident happened while my computer was idle - that’s why I think it must have been a mail (auto check for mails).

I have no other sub-system or resident program that should access files w/o my notice. And, yes, I’, running Win98se (w/all updates).
