Is there a version for the 64-bit architecture? I don't even know my Pentium 4 processor is a 64-bit until I notice it downloaded AMD64 packages during updates and some software installs.
Hallo,
in the majority of todays 64-bit distros (where the size really doesn't matter, 64-bit binaries always more bloated than 32-bit one) the ia-32 compatibility layer is usually present (or ready for installation). With CONFIG_IA32_EMULATION-enabled kernel and the subset of legacy IA-32 libraries, avast will work with no problem.
Just, when installing, you might need to tell the installer that the IA-32 (i386) architecture labelled package is the proper one, to override internal checks, for example:
dpkg --force-architecture -i xxxx.deb
regards,
