Lab Notes Be the early bird. It happens even to the most experienced users. Alert your network administrator immediately by paging, flagging down or sending up a flare.
All administrators worth their salt have an emergency plan ready for such events.
The best defense is good antivirus software that gets updated regularly and after every well-publicized virus epidemic. And, of course, a good backup routine helps restore the files that got broken. Viruses work fast, but they sometimes take minutes to copy themselves in e-mails or replicate to directories. Immediately run any antivirus software installed on the client. If it for some reason lacks antivirus protection, shut down.
