ClamAV question

[robbo007]

Hello all,

I have my ISPCP system all up and running on Debian (Lenny) and rocking...

I want to add a few more things, ClamAv and DSpam. I'll probably tackle DSpam later on but I'm pretty interested in ClamAV. Looks pretty sweet.

Can I just do a apt-get install and bob's your uncle? Or do I need to start hacking the config files for ISPCP?

Will it affect the speed of my server? I'm only running a AMD ATHLON 1400 processor with 2GB RAM. Not sure if its work installing?
Thanks,
Rob
