Microsoft has stopped macros from running because the source of this file is untrusted

Microsoft have added a security feature to help keep windows users safe from malware (malicious software) by preventing macros (instructions to run tasks) from running on anything that has been downloaded from an ‘untrusted’ source i.e. any site that has not been specified as ‘trusted’.
To prevent this error from appearing, VFD-Pro.com must be set as a ‘trusted site’.
