Summary
More Information
Mac/nVIR-A first infects the system file and thereafter remains resident in memory, infecting applications as they are executed. The Macintosh remains infected between restarts.
After a preset number of restarts or after a certain number of applications have been infected Mac/nVIR-A makes itself known by making the Macintosh beep occasionally when the computer starts or when an infected application is run.
If MacinTalk is installed then instead of beeping the computer will say "Don't Panic".
