The work aims to simulate how computer and biological viruses are spread.

The concept of something, other than a biological virus, being viral came into vogue just after the Internet became widely popular in the mid-to-late 1990s.

We should, however, treat the genetic sequences of pathological biological viruses with no less care than designs for nuclear weapons.

The "BioCoded" string seemed to have little to do with each other beyond being named after biological viruses.

A biological virus in this sense is exactly like a computer virus.

Maybe he infected it with a biological virus.

"Now you are talking about a biological virus again."

Instead, a biological virus must inject its DNA into a cell.

This is how the virus spreads - similar to the infection phase of a biological virus.

Software viruses are so named because they parallel in the computer world the behavior of biological viruses.
