Things to note when choosing or handling passwords:
The first thing to do is PREVENTION. You should make sure all the computers in your school are installed with anti-malware software and updated with the latest malware definition file. Note that: without updating with the latest malware definition file, the computer is not protected against the new malwares. Thus, malware signature should be updated regularly, say about once a week. You may also use a server to automatically apply the updated signature to all the machines.
Meanwhile, you should also teach your students to always scan floppy disk, CD and files downloaded from Internet before using them. Moreover, you and your students should backup programs and data regularly. This is the most secure way to restore the files after a malware attack.
If malware is found, don't be panic! Stop all the activities of the infected machine and disconnect it from the school network to prevent the malware from further spreading. Clean the malware using anti-malware tools or follow the instructions from anti-malware vendors. When the malware is removed, you can then restore the data from clean backup. You may also report the case to the Police when necessary.

However, if the machines are not installed with the updates, it will give a chance for the intruder to launch attack.
An intruder can make use of one machine as a stepping stone to launch further attack to other connected networks easily. If one machine that linked up with the school network is under attack, it may expose the whole network and computer systems to serious security risk.
Though it may take you some time for the update, your effort, time, and money spent should definitely be far more than this if your school network and systems are under attack and all the data are damaged.
If your school network is connected to the Internet, you should install a firewall to protect the network. An intruder can easily attack your school network by making use of the security vulnerabilities found in the software. Firewall can filter the unauthorised data traffic and prevent the intruders from accessing the important resource inside your network. However, you should make sure that the firewall is configured properly with appropriate access control, so that there is no false sense of security.
