When clamscan is interrupted it can leave temporary files in temp directory. I've implemented a trace feature in directory creation/removal.

clamscan will create a dirname.clamdir with the same name of the just created directory. This file is removed when clamscan removes the directory.

If the scan is interrupted clamwin will be able to find .clamdir files and remove the undeleted directories. Only directories at top level of temp dir are traced, since we don't need to known about subdirs, they will be removed recursively.

This features is already implemented in clamav svn, minor mods should be made in clamwin.

Expect soon a new beta to test this functionality.
