At least, it was commonly installed where I was around 2001. I don't think it was malware right away (it's been a while), but by the end of it's run, it seemed sketchy at best.

It's a tough balance to get right... you want to be approachable and friendly so that people will try your app. But you don't want to come across as a big purple gorilla or Clippy. I do like the penguin!
