I had browse through that link as well as searched around the internet
again...I found this link
The last sentence seems to imply that the Main repository does get more
attention (perhaps significantly more) attention from ubuntu. I would
like to see an anti-virus (anti-malware, I don't know these terms well)
program included in Main, that way there is some protection from other
sources....I would think that it makes sense for Anti-virus to be part
of the "base" system.
