According to an aspect of the invention, there is provided a method of protecting a user from a compromised web resource. The method may include monitoring a user's requests for trusted web resources to determine one or more web resources to be checked. The method may include querying a network database based on the determined one or more web resources to obtain historical data relating to whether any of the one or more web resources has been compromised at any time during a preceding time period. The method may include providing a predetermined response to protect the user if any of the one or more web resources has been compromised.

Protecting a user from a compromised web resource

A method of screening a software file for viral infection comprising defining a first database of known macro virus signatures, a second database of known and certified commercial macro signatures, and a third database of known and certified local macro signatures. The file is scanned to determine whether or not the file contains a macro. If the file contains a macro, a signature for the macro is determined and screened against the signatures contained in said databases. A user is alerted in the event that the macro has a signature corresponding to a signature contained in said first database and/or in the event that the macro has a signature which does not correspond to a signature contained in either of the second and third databases.
