We download virus updates daily and disseminate them to all participating PCs (even when you take your computer home, when connected to the internet your virus definitions will be updated). Also, we operate a server which provides Windows Security Updates quickly. Both types of security updates are required to keep a Windows machine operating safely and securely.

When you log on to the Lyon network (the box after user id and password will display LYONNET) your current anti-virus program will be UNINSTALLED and replaced with SOPHOS.
