Abstract

In a large corporate IT environment, the opportunity for an individual user to introduce a virus into the corporate campus network is large as all individuals typically have access to the internet. In order to prevent this from happening, IT organizations require their users to use an antivirus program to monitor their clients to block or disable any virus brought into the system and report its presence. The antivirus program is typically preconfigured to check a pre-specified server for updates containing information on how to identify and repair any damage for newly evolved or mutated viruses. In an emergency, the IT organization would have to send out a letter (email) manually to force a site wide update. The site wide update requires the end user to perform an action, so no coverage is ever 100%. This invention puts in place the infrastructure in a PC client that would allow an automatic and instantaneous update to their antivirus defense thereby ensuring all clients are upgraded in a timely fashion.

Antivirus Scrubbing on Demand

    In a large corporate IT environment, the opportunity for an individual user to introduce a virus into the corporate campus network is large as all individuals typically have access to the internet. In order to prevent this from happening, IT organizations require their users to use an antivirus program to monitor their clients to block or disable any virus brought into the system and report its presence. The antivirus program is typically preconfigured to check a pre-specified server for updates containing information on how to identify and repair any damage for newly evolved or mutated viruses. In an emergency, the IT organization would have to send out a letter (email) manually to force a site wide update. The site wide update requires the end user to perform an action, so no coverage is ever 100%. This invention puts in place the infrastructure in a PC client that would allow an automatic and instantaneous update to their antivirus defensethereby ensuring all clients are upgraded in a timely fashion.

In order to support an on-demand virus update model, if an emergency situation arises, the clients and the network interface cards (NIC) must be enhanced. The NIC cards must be modified to support a new magic packet command, similar to the Wake on LAN (WOL) magic packet. This is required to wake up a client for a virus update, if a system is powered off or cause an interrupt in a client if a client is currently powered on in order to inform the OS of the pending request to suspend current operations immediately and receive and execute an antivirus client program. In a preferred embodiment, an option is to modify the client to add a visible indicator such as a LED to the system cover to indicate that an emergency virus update is underway and to inform the user not to try to use the syste...
