/usr/bin/antivir -s --allfiles --temp=. -q .

The first line of this file gives the command-line for antivir (or other
scanner with similar functionality). The defaults supplied in this file
request a recursive scan, including all files and generating no output,
starting in the current directory.

The default command also specifies that temporary files should be created
in the current directory--in hopes that they fix antivir so that the
option actually works someday.

Note that antivir must be specified by full path: if it isn't, it won't
be invoked at all.
