virus attacks

Routes of infection:

Outside connection (internet, T1)
E-mail attachment
Floppy disk from a student (or teacher)
CD from a student or teacher

Effects:
The effects vary by the particular virus.
They range from benign messages.
To e-mail spamming.
To erasing files off of the PCs or server.

You need a complete anti-virus policy and monitoring effort.
All systems need anti-virus software installed with full file scan enabled.
You also need to update the software constantly.

Then, you need to setup policies to limit the way users are allowed to bring new files into the system.
It would be a good idea to remove the floppy drives from all PCs that students have access to.

Use a mail system other than Microsoft Outlook for the client systems.
