She says:

"1) No, in 14 years I have never known anyone on an Mac to catch a
virus, except an extremely rare (like once ever ten years) Word Macro
virus, easily conquered.

2) ClamAV doesn't get updated often enough or cover enough of the
territory to matter. Ignore it.

3) if you really want anti-virus software for the Mac, try Virus
Barrier from Intego, though I've never heard of anyone every having
caught a virus using it (but no one NOT using it has caught a virus
either). This is not just me. This is me, as an active member of
lists populated by literally thousands of Mac users over more than a
decade.

4) As for forward delete, I gather that it doesn't work one-key on a
PowerBook, but on my full-size keyboard it has a one-key
forward-delete.

On my old iBook I have to use Function-Delete. There are a number of
keyboard-mapping third-party programs such as iKey and
KeyboardMaestro that might solve this for her. But I don't know for
sure.

That's all."
