Summary

This is one of the oldest viruses around, but it is very rare. In fact, it may even be extinct, apart from copies in the hands of virus researchers. The original virus is 419 bytes long, but several minor variants are known, with slightly different lengths.

Like the Lehigh virus it can be stopped simply by making .COM files read-only. Most other viruses are not bothered by this, however.
