The SigWizMenu program places it's modifications in two files; SigUser.conf contains the SILVER rule set signature, and SigSettings.conf contain the rest of the custom signature information.
Your old String Matches are still active and will function until you remove them either with your management console or by manually editing packetd.conf. The signatures created with SigWizMenu are much more effective than the old String Match signatures so it would be worthwhile to convert them.
