Install on Ubuntu Mischievous Meerkat

I am a newbie to Linux (though with long Windows/Mac experience).

I would like to install Avast for Linux; the requirements stipulate GLIBC and pthread. When I check in Synaptic Manager, GLIBC shows no hits, while pthread only has pthread-stubs0 and pthread-stubs0-dev available for install. If I do locate glibc in terminal, I get /usr/share/man/man7/glibc.7.gz. Would I have the man pages for glibc if it were not installed? If it were installed, shouldn’t locate locate it? I’m not sure if I fulfill the requirements or not.

If I need to install anything prior to installing Avast, would someone kindly provide instructions on where to go and what to do? Are there any ‘gotchas’ that I need to watch out for, or will right-clicking/install with Ubuntu Update Center on the .deb package suffice?

many TIA,
shnew

Hallo,
glibc is the main userspace library of the whole system and is in some, usually very backward-compatible form (as we all always hope:) already present on your system. Threading library is in turn part of the glibc suite :).
