Limit data port range.
Default: 2048

libclamav. This option disables recommended options and
allows you to enable selected options. DO NOT ENABLE IT
unless you know what you are doing.
Default: disabled
ScanPE PE stands for Portable Executable - it’s an executable
file format used in all 32-bit versions of Windows
operating systems. This option allows ClamAV to perform a
deeper analysis of executable files and it’s also
required for decompression of popular executable packers
such as UPX.

executables and mark them as Broken.Executable.
