Registry utility I would love to have

I don’t have this, but I certainly would use it.
A simple utility to do search and replace in the Microsoft Windows registry.

Ideally it would do the following:

• Specify a list of values to delete – it would then remove ALL those values
• Specify a value and what to replace it with
• Specify a key and what key to replace it with
• Specify a key and what value to make it

My immediate use is removing entries that a virus (WORM actually) has entered in. Using regedit is a pain pain pain!
