Malware manufacturing is a business. It creates income and employment all around the world.
If one day there was no malware at all, then a lot of bad things would happen. Millions of people would have no jobs, companies would go out of business, the stock market would crash, etc.
So malware does have its good points and is here to stay.
Of coarse nobody wants it on their system and will pay for protection, malware education and to have it removed.
Kind of like if their was no bad people then we wouldn't need prisons, but prisons create a lot of jobs and employes that will have to work for free which we all benefit from.
In order to have good, there has to be bad.
Thanks.
