"I got this email from a vendor. They changed their name or something and it's all in French. Every time I try to open the attachment, I get a warning about something called macros."
Does this company, from Birmingham Alabama, typically conduct their correspondence in French?
"No."
Then it isn't from that company. Delete that and please refrain from opening strange attachments.
But, it SAYS it's from them!
It's going to be a long day. I can tell already.
