В оригинальном файле написано:
# 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, FSG,
# and Petite.
# Default: enabled
#ScanPE
# This option enables scanning of Microsoft Office document macros.
# Default: enabled
#ScanOLE2
# Enable internal e-mail scanner.
# Default: enabled
ScanMail
# ClamAV can scan within archives and compressed files.
# Default: enabled
#ScanArchive
# Due to license issues libclamav does not support RAR 3.0 archives (only the
# old 2.0 format is supported). Because some users report stability problems
# with unrarlib it's disabled by default and you must uncomment the directive
# below to enable RAR 2.0 support.
# Default: disabled
#ScanRAR
т.е. по умолчанию уже:
включена проверка файлов PE,
включена проверка документов MS,
выключена внутренняя проверка почты,
включена проверка архивов,
выключена внутрення проверка архивов RAR.
Так ли это?
