This is software we use to protect our systems.

ZoneAlarm
Pro
This is a software firewall. That is it protects your computer from
access via an Internet or other connection from rogue, virus and other
malicious software programs and attacks. It works by keeping a record
of permissions for each program on your computer that uses a dial
up connection. We've never tried to configure it for local access
denial or control but as Port numbers are available it could be used
to protect a workstation on a network. |
This should really be on all machines that have an Internet connection;
but must be on all that use one of our static dialup accounts. There
are other products but this is the best and most reasonably priced
we have found. The initial cost is USD and the subsequent annual
subscription is USD
It is very configurable but will keep popping up for the first
few days asking if such and such a program can have Internet access
or operate as a server. It is fine with IIS or Personal Web server
and Apache web server is also okay if you have these running on
your computer.
As those clients with ADSL or ISDN and perhaps also using MS Exchange
are on a static IP address, and therefore vulnerable to scanners
looking for such targets Zone Alarm is a less expensive option of
a hardware/software firewall.
If you have advert sponsored software that tries to call home secretly
then this catches it. Opera is fine, one can see the banner ad trying
to refresh and once Opera is allowed one need not be concerned again.
However there are plug—ins in Internet Explorer such as Jini
and the new.net names resolution plugin that call home without IE
being open. Basically I deny everything if ZA pops up unless I have
a program open and know what it is going to do. Fortunately one
has a choice of allowing something on a 'this instance only' basis
so if veering towards a 'probably all right' decision something
can be run just once. Then you can look at task manager or cookies
etc. and try to track what prompted the access warning.

AVG
Anti Virus.
This is a free virus utility that on occasions has beaten the bigger
names.
|
Can one beat free? Yes. This download is reasonably small at 3.2Mb
last known and installs easily. It does all the things that you
might expect, including e-mail checking incoming and outgoing, and
updates as per your own settings. It runs a scheduled check-up -
but you cannot choose the time. It runs the day following your setting
it to 'on', and then every day at the same time. Better get up early
one day to do this.........
It runs alongside ZoneAlarm
Pro
without hassle (to date) and also with Fixit Utilities, although
the virus on-line is disabled in Fix-It.
It was the first of the three we use to detect nimda but cannot
kill it or move it to the vault, one has to delete the nimda.dll
file by hand.

Fix-It Utilities
3.
Does all the stuff one would expect of a general clean up utilities
program.
|
We started off with Alan Solomon's stuff because he came from a
machine code and CP/M background but when he sold up the quality
took a nose dive so we moved to Peter Norton because his early stuff
was good at keeping machines clean - the disc defrag was really
good. Then he sold up and we moved to the first version of Fix-it
'99 and stayed with that for a while until the new Norton Systems
Manager 2002 came out. But we've gone back to FixIt with version
3 as it lives peaceably with everything else on the machines, while
Norton does not.
Reasonable on the Windows registry. I've never been impressed with
any of the Crash catchers and don't run this one either.

Tools
from Symantec
It's bad enough getting a virus in; but not all virus checkers can
remove it. Some will only quarantine the attachment, some will repair
damage. |
Click
here for the latest virus removal tools.
This site has proved the fastest to publish virus repair and removal
tools in our experience. Often Symantec will put the removal tool
here in advance of updating the software. Should you have a live
virus on your machine that has got into files then these tools may
help.
Have you got a clean boot floppy disc?
If not I strongly suggest that after a full and complete virus check
of your system you create a boot floppy disc, or two, and keep them
safe.
Why? Because live virus often hide themselves in your computer
memory; and can still be there after a virus check and clean. By
rebooting your machine with a clean boot disc, then running the
virus checker you may avoid this. It's no longer a sure thing. If
your virus program has the ability to make a clean boot disc then
take the option...

Boring Explanation:
It's not unusual for me to be asked "What do you use". In fact
it's been happening often enough, and I can never remember all the details,
to force me to take the time to write this page. Then I can give brief
response and direct our clients here.
Software purchases are often a compromise. Very few do exactly what one
would like at a reasonable cost. I give reasons why, but also notes about
what I find unhelpful, irascible or otherwise a bother.
Short Explanation:
Because it makes sense.
