Best way to delete Internet Cache, cookies, and free space

Is there a program that can do this?

[Compworld]

I need a program that can delete my Internet Cache (both I.E. & Mozilla (Firebird & 1.5)), cookies, and wipe the free space to ensure that none of that data is recoverable. Is there a program that does this? Besides a low level, I need something that can do the same thing but only to the specified items that are listed above.

Any ideas?

Thanks,

You could write a batch file that called some sort of wiping software, like PGP, from the command line to zap those directories while you sleep...
