Once the computers and network are configured, as we also do, even for
our Nix based networks, there is little investment in time, possibly 1
hour a month to check reports and file them for compliance audits.
My own computers, in my home, 8 servers (some have 4-6 virtual children
OS's) and 7 workstations, don't cause me any time spent on malware
because they are properly secured, the networks are secure, the firewall
appliance is secured and filtering....
I spend just as much time installing Nix updates for the OS and apps as
I do Windows updates, but my win machines support more hardware THAT I
USE than my nix machines.
The nice thing about Linux is I don't have to worry about "properly"
configuring my computer. And that's a huge advantage for a home user. And,
let's face it, you're the exception, not the rule. Most Windows users
actually believe that, if they keep their Windows OS up to date and update
and run anti-virus software, they won't get viruses and malware. Obviously
they do get infected anyhow, and it's worse than that -- they're registry
will often get corrupted because... well, no one really seems to know
exactly why. BSOD, KSOD, or just a general registry corruption? Backup (if
you can) and reinstall. How many times a year do people reinstall Windows
because of viruses or general malware, or even bitrot? A lot. My nephews
do it on a regular basis -- when Windows starts slowing down they
reinstall, so they can get that "new" performance. Do a Google search and
see how many times "reinstall" is suggested as a Windows "fix."
I don't have time for the hassle.
