I ran a DOS batch file I created myself. Avast Free flagged it as “potentially dangerous” and quarantined it w/o asking me to confirm first. >:(
Then, when I go into the Virus Chest to restore the file, click the arrow next to the Delete button to change it to “Restore”, nothing happens. The button doesn’t change. The file does not restore. Fortunately, I saved a copy elsewhere because I can’t find the Quarantine folder it was supposedly moved to (I found "C:\Qoobox\Quarantine", but it does not contain the deleted file. Nor does the folder AVF was installed to.)
And adding files to the Exclusion list is FAR too complicated to prevent this from happening again (I eventually found it under “Settings | General | Exclusions”.)
