FDAV is an anti-virus scanner designed especially for FreeDOS and utilizes the virus-scanning engine of ClamAV. It provides a minimal command-line interface (for a more powerful command-line interface, use clamscan from the ClamAV package), but was mostly written to provide an attractive text user interface, designed to imitate MSAV in many ways. It is available under the GPL.
To compile FDAV, you will need the following libraries:

FDAV can be downloaded at http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/system/clamav/ and the relevant packages are fdavx.zip (binaries), and fdavs.zip (sources). fdavx.zip also depends on clamdbx.zip in the same directory, if you don't already have it installed.
