Just a note:
From my experience month or so ago, Avast listed there is not freeware...
Yes, you get to scan your computer for free, but there it ended, at least to me...
here are some more links:
free Java development tools - good softwares if you are interesting in Java languages...
Putty - very good and free Telnet / SSH Client...
