Its probably useful to know the difference between a secure delete, and a regular one - a secure delete overwrites the sectors that were used, while a regular one merely marks it as unused.
When I need a file level secure deletion on windows, I tend to use eraser (for a GUI) and sdelete (for scriptable or command line use) , on windows and shred on linux to delete files.
Naturally until you're sure this works, it wouldn't hurt to check with a recovery software to see if it actually worked.

Personally I use Axcrypt (free) to encrypt single files and folders. Axcrypt has an option to "Shred and Delete" which asks if you want to "overwrite the file with random data and permanently delete it?"...BAM! Now that's what I'm talkin bout! :)
