BonziBuddy? is rumoured to be the evil spawn of some incarnation of TheDevil? . . .

It's evil, it's purple, and it's a FRICKIN' MONKEY! . . . That monkey . . .

Once installed it infests your computer and hijacks your desktop, it latches its invisible TentaclesOfEvil? into wherever it can, and the only way to rid yourself of its sickness is to replace your hard disk. (Some say reinstalling your OperatingSystem is sufficient, but you never can be sure . . .)

BonziBuddy? and most other software of this type, usually referred to as ScumWare?, can be removed by Ad-aware. In some cases the ScumWare? will try to remove Ad-aware first, and/or prevent lavasoft's download site from resolving so you might have to download it via an uninfected computer. This type of software generally only affects Windows systems; if you're running Linux or freebsd you'll never be bothered by large purple monkeys or YellowLinks? again

Sometimes used as a practical joke against workmates, however this can be likened to killing your workmates first born so use at your own peril.
