have often strongly recommended that you take steps to protect yourself
from viruses and even aired our bias for Norton over other products. Whichever you chose we do hope that you have taken those
steps. Note that the latest
versions of both Norton and McAfee automatically check to see if there are
new "virus definitions" available and, if so configured, will
automatically download those definitions and install them.
A very nice feature if you might be considering an upgrade.
have not, until now, recommended a "firewall" to any but our
"always on" (DSL and cable modem) clients.
In the past we had recommended either the free Zone Alarms or
for-fee Zone Alarms Pro. After
encountering various troubles with our local area network with the free
Zone Alarms, we downloaded and installed Norton Personal Firewall.
reporting feature has brought a major concern to our attention: port
scanners. These programs
cycle through Internet Service Providers (Earthlink, AOL, etc.) looking
for attached users and then probing these users machines looking for
unprotected ports. When one
of these is found, the person on the other end can then browse your
machine looking for anything that might be of interest or value
(passwords, credit card numbers, bank account numbers, etc.).
net of it is: you do not have to be "always on" to be exposed.
you have a simple, one machine configuration with no local area network,
Zone Alarms works fine and is free. You
can download that software from http://www.zonelabs.com.
those with local area networks I recommend Zone Labs Pro (http://www.zonelabs.com),
Norton Personal Firewall (http://www.symantec.com/sabu/nis/npf)
or the Network Associates (they make McAfee Virus Shield) product PGP
(http://www.pgp.com). You can
download any of the three or purchase the CD for either of the latter two.
