Can someone explain in very basic terms what the difference is between
anti-virus and firewall.
 
Hi,

Basically:

An antivirus program is one that is design to scan files for the potential
of being an infectious agent. This could be in the form of a file downloaded
from a web site or one received in email, but is not limited to such.

A firewall is a program or hardware that is designed to prevent unwanted
intrusions into a system from outside. Any system connected to a network can
"talk" to another one. Some out there are infected with various bugs and
actively attempt to contact an "open" system and infect it as well. A
firewall prevents the outside system from invading the protected one.

An anti-virus program looks at *files* and tries to identify and delete
those files that are malicious (viruses, worms, trojans, etc).

A firewall looks at *access* attempts to the computer and prevents them
(without knowing anything about whether the attempt is malicious or not).

If you have a stand-alone computer not connected to the internet, you don't
need a firewall. But you still need an anti-virus program because you are
still subject to getting viruses from removable media: diskettes, CDs
(finding a virus on a CD is rare these days, but not unheard of), thumb
drives, etc..
 
You highlighted something for me that I will find very useful:

I never knew about operators despite using Google and it's
predecessor for a number of years.

Thanks.

One of the operators not listed is "group:". It comes in handy when
searching Google Groups to limit the search to a particular group or a
specific set of them, as in:

"Windows XP Pro" group:microsoft.public.windowsxp.newusers

+EFS +certificate group:microsoft.public.*

Other than group:, I mostly use the site: and define: operators.
