Virus

Where do virii come from? Why do they exist? Why do they come to me? How I suffer! Never complaining, always cheerful, just getting on with it. Aye right!
I am sick of this one, and it seems to go on for ever.

But where do they come from? Why do they exist?
Those little bugs, so complicated, so cleverly designed, cause so much damage. Look at the cold or flu virus, tremendously well made. The picture of the cold virus shows how complicated it is.

Now if God created them, what purpose do they serve? If they evolved, to what end? I just do not understand their purpose, but I know the damage they cause. if there is one thing I would like to do it is either lose them all, or adapt them to some useful purpose.
