Is this really a Notes-specific one? It looks like it's pretty general from the posted e-mails.
Yes, here we go again. I really wish these virus writers would get a life. I also wish microsoft made a decent operating system... We've got those lab computers running windows, but I'm way too busy to screw with them anymore. Maybe I'll just tell our lab coordinator to update the virus definitions, etc. |
