Abstract: According to a first aspect of the present invention there is provided a method of protecting a computer system from malware, which malware attempts to prevent detection or analysis when executed in an emulated computer system. The method comprises determining if an executable file should be identified as being legitimate and, if not, executing the executable file while providing indications to the executable file that it is being executed within an emulated computer system.

Abstract: The present invention relates to a method for synchronizing files between devices between two devices. The method includes creating a rule to control the synchronization of the file. The rule includes at least one condition for synchronization which is dependent upon a property of a device.

Abstract: A method for determining appropriate actions to remedy potential security lapses following infection of a device by malware. Following detection of infection of the device the device undergoes a cleaning operation. As part of the cleaning operation infected electronic files and any other associated files or objects are removed from the device. From timestamps associated with the infected files and associated files and objects, either directly or from another source such as an anti-virus trace program, the time of infection can be estimated. This allows the system to reference timestamps on the device to determine the source of the infection. Additionally, if the type of infection is identified timestamps on the device can be used to determine where there are particular areas of vulnerability due to user actions on the device.

Abstract: 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.
