Should I be using anti-virus & spyware for Linux as well?
Need? Probably not, no.
However, if you get sent a word document with a macro virus whilst it won't effect you, you might inadvertently pass it on to other Windows users by accident, for example.
If you care enough about this unlikely threat, you could consider installing KlamAV [klamav.sourceforge.net] which is the only open source real-time AV scanner for Linux, as far as I'm aware. It's a front-end for ClamAV, which is usually used by email servers to make sure mail passing through is clean.
I don't believe there is a direct equivalent of anti-spyware or a personal application firewall for Linux, but you're unlikely to need them.
