  • Virus detection and removal system and method for network-based systems
    Patent number: 7080407
    Abstract: An enhanced virus detection monitoring (VDM) system and method suitable for use with network systems, and in particular electronic document control systems (EDCS) is disclosed. The VDM system intercepts files and documents before they are made available to other users (“check-in”) and inspects the files/documents for virus infection. If a virus infection is found in a file or document, the VDM system invokes anti-virus software to disinfect the file or document. Once the virus has been removed from the file or document, the file (or document) is then made available to other users of the system. If the virus cannot be removed, the file (or document) is not allowed to be checked-in.
