MACRO SECURITY
Macros can do many things.....write to the registry, delete and change files and
all kinds of neat things. You can bugger up your computer easily by running a macro with malicious code in it. The ones you write yourself can only do what you have written. What they can do is up to you. To protect yourself, don't download files that contain macros unless you trust the source or the macros have a signed digital certificate. Always have your macro security at Medium or higher. To get away from the security warning on your own workbooks with macros, you can use the SelfCert tool to digitally sign your own workbooks for use on your computer only.
