Clamav Backports

[tricolorpoa]

Hi there,

I am testing Clamav with my Ubuntu samba server but when I run

$ sudo freshclam
ClamAV update process started at Tue Jul 7 11:54:37 2009
WARNING: Your ClamAV installation is OUTDATED!
WARNING: Local version: 0.95.1 Recommended version: 0.95.2
DON'T PANIC! Read http://www.clamav.net/support/faq
main.cld is up to date (version: 51, sigs: 545035, f-level: 42, builder: sven)
daily.cvd is up to date (version: 9540, sigs: 39917, f-level: 43, builder: ccordes)
I need a help to add backports to my source.list and then get the newest version of Clamav.

Thanks for the moment.
