The functions of VERV's command-line switches include:
- Reading the virus to be tested from an image file,
instead of from a normally-infected object; this can be
useful, for instance, in testing a boot-sector infector
that has been received as a binary dump of the boot sector
rather than on diskette.
- Overriding the default
virus-description file
(contained within tne program itself), allowing easy testing of
new or experimental descriptions.
- Producing detailed progress messages and data displays
during processing, to help pinpoint differences found or
errors encountered.
- Specifying that, rather than using a CRC, VERV should compare
the relevant parts of the object to be tested with a standard
sample of the virus stored in an image file, or a standard
infected specimen.
- Producing a dump of the virus image, after all degarbling,
but before any zeroing has been done.
This image can then be used for storage, analysis, or transmission,
or for later use as input to VERV for byte-by-byte comparisons.
