Updating portage tree
Following extensive testing of clamav and the packages that use it in the backports repository, they may be updated to a newer version.
Unlike most operating systems, Funtoo does not ship with a GUI pre-installed.
Freshclam should perform these updates automatically. Instructions for setting up Freshclam can be found in the Clam AV Manual or in the documentation section.
If your network is segmented or the end hosts are unable to reach the Internet, you should investigate setting up a private local mirror.
We recommend running the Clam AV Stable Version on production systems. Find Win32, Mac OS X, Linux & BSD signatures in the Alternate Versions section.
For Clam AV to work properly, both the Clam AV engine and the Clam AV Virus Database (CVD) must be kept up to date.
