[Nottingham] Anti-virus (and kmail address book)

[David Wolfson]

Anti-virus:
I've been meaning to ask this for a while, but the latest news item about 
Billy G's trouble with virus gangs reminded me. I'd never leave a windows box 
running without anti-virus running, but have never bothered too much on Linux 
machines. I guess this is probably niave, but thought I'd do a quick 
survey/get some advise. 

What does the nlug collective use? 
Do they use anything? 
Are there enough linux viruses out there to worry about?

On windows I use the latest Sophos, which has an active monitor, all the usual 
guis, and does auto updates. Is this level of functionallity available in 
'nix?

kmail:
So, I went to write this mail, and found that I can't see/edit my address book 
in kmail. The only way I can 'see' it is with the '...' button in a compose 
window. If I add an address book button to the tool bar, its grey'd out... 
How do I get at it?

Cheers,

Dave
