Hi all I am trying to figure if I really need Wormguard. Currently protecting my computer (XP Pro) are Zone Alarm Pro 4.0, F-Prot antivirus,TDS-3,Spybot, Adaware, and lastly Abtrusion Protector. The last is the reason I ask. Abtrusion Protector when installed scans every file on the computer that can execute code, and records it and a CRC thumbnail. Then when anything new tries to run, it blocks it and alerts. (Yes it does have an install provision) I have tested it well, and its great. What would Wormguard offer on top of all this.
