BugBear is an unusually eeeeevil virus. It's my understanding that it can in some cases circumvent Norton AV. (Scary.) I'm glad you caught it without any trouble! IMO The "Darwin" theory is a little rough in this case. Not all computer users are as computer-literate as we, nor do I think that's a matter of stupidity. How many of you have grandparents, for example, who have computers but don't understand all the internet-related issues? Are they stupid if they open an innocent-looking attachment? Not necessarily. Innocently ignorant, is more like it. I see a lot of anti-.exe sentiment in these forums, but it's important to remember that .zip files also sometimes contain malicious scripts. I'm sure we all agree that pretty much all downloads should be scanned with AV software prior to opening or executing.
