MACRO SECURITY ANNOYANCES

AVOID MACRO VIRUSES

The Annoyance:

VBA is a powerful language, but it can get you into trouble if you're not paying attention. Macro viruses, which I never heard of five years ago, have become the bane of my existence! How can I make sure my people only run macros I know are safe?

The Fix:

First, purchase and use antivirus, antiworm, and anti-Trojan software. This is particularly important in Excel 97 because this version has no macro security setting. If you're running Excel 97 and you absolutely can't upgrade to a more recent version, make darn sure that your antivirus software is up-to-date and it's set to actively scan all incoming files. If you have a computer you use as a gateway to the Internet, you should strongly consider putting one antivirus program on the gateway and a package from a different provider on your users' machines; if a virus or worm slips by one of them, the other will probably swat it.
