You know, I really wanted to leave this thread alone, since I thought
I'd made my case, but I have to comment on this. I do not see that
adding AV would be a 'waste of time'. It does not take that long to
install and cron a full scan every night. What is so bloody difficult
ANY internet facing system is at risk. And every precaution you can
take SHOULD be taken. This includes updates and training the user to
understand the basics of system security. But not including antivirus
is just asking for trouble.
I fail to see where these blinders have suddenly come from. It's
appalling to me that this type of attitude still prevails. That a linux
system is invulnerable to viruses therefore AV is not needed. If you
are so unworried about viruses, I suppose you aren't worried about
rootkits either? Those are much more common on linux that windows
(maybe until very recently). Do you not routinely do a scan with rkhunter?
I just can't see how not running AV is ever considered 'OKAY' on any
system. I give up. I just cannot believe how many people fail to see
the sense in that one simple precaution.
I've rebuilt way too many compromised systems to trust that it will
NEVER happen to me.
