Basically, computer errors are the result of a number of things that may or may not have anything to do with the way the computer is used. They "operate" whenever there's a conflict among commands.

We wouldn't be surprised to learn if other motivations behind spreading viruses were similar to this person's, but that doesn't justify the damage that viruses do. Innocent people become pawns for the evil plans of others who've convinced themselves they're doing the "right" thing. To protect a computer from getting a virus, or clean a virus from a computer system once infected requires the use of an antivirus utility. Computers are everywhere.

Although the prices of computers are decreasing, they can still create a hefty expense especially if you need additional peripherals described above. Through a wide network of user involvement, the software in question is enhanced and debugged without costs or administrative politics. Traditionally, software is developed behind closed doors. A team of professional coders build it but the community at large isn't part of its conception. It's costly to produce and as you can probably guess, that cost is passed on to the end user: the consumer. But be careful not to confuse these newest toys with sandbox devices. Sandbox devices are tools that come pre-loaded with things like calendars, calculators, and a notepad. What differentiates them from smartphones is that users can add (download and install) additional programs to smartphones and they seemingly become mini portable computers for the people who use them.
