What worries me is we haven't seen *either* an actual damaging virus (imagine if the last 2 lines of Mydoom were "sleep(4hours); exec("format c:);") or a "sleeper" virus. At least we can console ourselves with the thought that a stealthy sleeper virus would almost by necessity have a very low burn rate, and thus take a long time to compromise a significant number of systems (if somebody has a way they'd like to share to spread quickly while remaining stealthy, feel free to comment ;) I wish I knew which one to be more worried about the lack of.. ;)
