how to prevent access to hard drives through firefox after being hidden

[steel man]

Is there a way to prevent access to hard drives through firefox after you have hidden them. i went through "regedit" from the "run" command and also used "1st Security Agent" program to hide my hard drives, i have got it to the point where you can not access my c: through "IE" and the "Run" command but you can still get to my c: by typing "c:" in the address bar in firefox. is there a way to prevent this?

P.S. is there any other way to access my c: , and if so how do i prevent that also?

Thanks
Larry

Use policy.
How?
Turn off the easy share in folder->option...
Then change security on those folders(disc), which you don't want to be accessible.

! :!: ! :!: ! You could remove access for the system on hdd "c:". Better way is to "lock" those folder, which you don't want to be accessible for you (Games,work). Or remove access for you to view them.

I could send you screenshots how it should be done, but I have a non-English windows XP (CZ).
