YES! It scans *inside* ZIP, TAR, RAR etc. (Maybe these have a 4 GB limit too?) If ClamAV can't handle files bigger than 4 GB, then it isn't very suitable for modern computing. Most computers sold today support 64-bit addressing. Windows 7, 8 and 10 can be either 32 or 64 bit, as can Mac OSX. And of course Linux started supporting files over 4 GB many years ago -- even before it supported 64-bit memory addressing. Finally, DVDs have held more than 4 GB almost forever, Blu-Ray is lots bigger, and individual digital video files can easily exceed 4 GB (especially HD or UHD source files, which have little or no compression). P.S. The usual way to "open" an ISO is to "mount" it. This operation is usually performed at a high privilege level (e.g. root) which means that if a malicious ISO were able to exploit a vulnerability in the code which decodes the ISO metadata/headers (buffer overflow comes to mind) it could cause major system damage. _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net http://lists.clamav.net/cgi-bin/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
