Ewido & other Spyware programs on PE

[nutmonkey]

This is my first PE cd so take it easy guys Ive created a few unattended XP cds that have really saved some time though. Ok this is the first of a few questions I may have on my task to create my own BartPE bootcd, when I add Ewido, Adaware, etc. they all scan the X: drive by default how can I make it scan the c drive by default like it does on a regular install? Thanks in advance
