The best way to fight computer virus?

By metville ·
I have a machine run by a windows-based computer. This computer is hooked-up to the network via tcip (Therefore it is visible on the network all the time). The drives are shared because it is a requirement by the program to run the machine. It is also shared so parameters are downloaded via network. This computer is usually prone to virus attacks eventhough NAV is installed. To limit virus infection to a minimum, I setup a dummy pc. This dummy pc is now connected to the network and it used to download parameters. It is also installed with NAV. The machine's computer just acts to run the machine. However, it still connects to the dummy pc via peer-to-peer to download the needed parameters to run the machine. A script was made (installed on the machine's computer) to automatically download the files from dummy pc to machine's pc. The script automatically connects and disconnects network communication between the 2 computers. Simply put, I setup a dummy computer to make sure that files that is going to my machine's computer is already free from virus. My question is, is this the best way to protect my machine's computer from virus infection? Our machine is critical and responds erroneously when computer is infected with virus. If it's not, what other means can you suggest? Will using Winsock instead of tcip lessen probability of virus infection?

You have basically set up a proxy, it will be sufficient provided
BOTH machines are running antivirus and the antivirus is
updated constantly. Take a look at symantec's site and search
for information on how to use the intelligent updater. You can
script a task fairly quickly to check for updates every hour and
pull them down immediately. This will mitigate a lot of risk.

I would also make sure that you are using password protection with your share. Setting a password for each share will cut down on alot of infections to the systems.

I am going to buck the trend here. while the system you have set up can provide some protection against viruses etc. it is not a complete solution. in order to identify the best aproach you need to know something about your controller. Yeah, its a PC, but it is functioning as an embedded controller, correct?
Are you running Win XP? if so, make sure your ssystem is up to date with all critical patches and service packs (SP2 for XP) next, get a desktop firewall since you use NAV, I would recommend either Norton or Symantec firewall
lock down all network access except for that needed to transfer the files. turn on real time virus protection. kick the priority of your control program up a notch if the machine operates erratically. get rid of the dummy PC. update your virus definitions weekly or more often.

please rate my answer

The answers you have received have been great but I would use a Linux box as a poxie server. It is secure from the install because no ports are open unless you open them. And you can get a consultant for a good price to help you install and learn how to run it. Your setup is fine for a small company but you need a edge and using a O/S that is secure from install will help. MS offers front end and back end but the cost will too much for small companys. Winsock, TCP/IP it will not help if people in your company still open emails that are from people they dont know or go places they shouls not. Or if you leave ports open that can be used by people/programs that you dont want used.
Best idea is to read up on every thing on securing you network and go to to read up how to install and configure your network.

Which brings up an important issue. That of a firewall. Make sure that you have a strong firewall that will only open the ports you need to in order for you scripts/applications to work properly. Close off anything else. Doing so will lessen the chance of exploiting security holes inherit in Windows and the IP protocol itself.

I am sorry, but I hate Nortons with a passion.

You can be infected by going to a website. You don't have to start a download just access the site.

I have had to clean more computers that run Nortons. The client will call and say "Nortons said it found so and so but didn't do anything about it."

I run and recommend the following.

This is by Computer Associates. It evolved from Inoculate. One of the best corporate AntiVirus programs ever.

I have yet to see something get through it on my machines or any of the 100 or so client computers I have installed it on.

It's firewall is easy to configure, and provides a excellent log of activity.

As of today 7/29/05 you can get the first year free.

Good Luck

First off if the AV is not catching the virus and stopping the virus you need to get a new antivirus.

If the Antivirus is kept up to date and is good at its job you should not have to worry.

NAV is not the antivirus I sell to my clients.

Their eArmor is one of the best I have ever used. And I have used them all. It will detect and remove virus that NAV will not.

Any antivirus need to have daily defination updates.

Good Luck

Most virus are 6k to 10k thats the given that over looked virus most be small in size to download fast and cause damage the reason most get hit is that the defintions are not updated.
