This has been verified and will be fixed in the next release of
VIRUSCAN.  Since the Jerusalem (and sundry variants) infects overlays
in addition to .COM and .EXE files, it's always a good idea to run
SCAN (and CLEAN) with the /A option, or use the /E option and list the
extensions you would like to add.

It's particular to the Jerusalem-related virus string.

The next release (incorporating the fix) is scheduled for mid-June but will
probably be released earlier because of this.
