What is a Virus, Worm, and Trojan Horse..Continued

• Trojan Horse- Now, there are Trojan Horses and there are viruses, but there's no such thing as a Trojan Horse virus. In fact, the very definition of each precludes any chance of there being such a thing. A Trojan does not replicate. Viruses do. That fact alone means there can never be a "Trojan Horse virus".

The future

• In the future, I think we will use computers for every single thing in life. They will drive our cars, cook, for us, and mostly just run our lifestyles if we keep advancing at the computer pace we are at right now. You never know, in 2036 we could have an iHouse by apple. It could be a house just made by computers!
