This concerns computer hackers and viruses.

A computer genius is a popular soul,
Who cares for all others who aren’t in the know.
A virus designer must be caught very fast.
Don’t be surprised, they are snakes in the grass.

Allowed to grow freely eating gators and deer,
Like Burmese pythons, in Everglades and near here.
Innocent victims write children’s stories and poems.
Snakes live to hurt others, and not seeking coins.

A slime on it’s belly like a mollusk or snail,
To be cast in a prison without judge setting bail.
They shall be caught and forgotten virtually quite fast,
But the words of a poet, are some things that will last!

Robert Edgar Burns
