Matus is correct. The issue has nothing to do with what your file system is. It has to do with scanning archives that use the HFS+ filesystem. Specifically, HFS+ is commonly used in DMG archives.

since the patches only mengion DMS files and HFS+ files, I don't see any
reason they should affect BTRFS filesystems. >Will it be affected even if the client uses HFS or dmg?
It does not matter what the client uses. ClamAV fill scan files as you pass
them to ClamAV.
ClamAV can scan filesystem images, unpack those filesystem images and scan
files within those filesystems.
This is where bugs were fixed - those images were parsed incorrectly which
causes the mentioned bugs.
