And remember that DVDs and flash disks that may be created from an ISO are often booted from to install whatever. This could mean your system is compromised at birth. Also, splitting files may split in the middle of a signature. Plus, if an archive file is split, the pieces will no longer be proper archives. P.S With regard to files bigger than 4 GB -- "nobody needs more than 640 K of RAM", "4 billion IP addresses are more than enough", "31 bit time stamps will last for 70 years", "64-bit addressing is unnecessary for home computers", and, "disks with more than X 512-byte blocks are overkill". (Note that X has had to have been increased 7 times -- from 508 MB to 2.1 GB, to 4.2 GB, to 8.4 GB, to 33.8 GB, to 137 GB, to 2 or 4 TB, and now to 128 PB with LBA 48. This lack of foresight makes the Y2K issue seem like good planning.) _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
