While this may be an oversimplification, it is fundamentally true. When software does damage hardware, it s almost always the result of a deliberate act. The reason I tell you this is that many people are afraid that somehow their computer will break if a program crashes. Don t worry. In most cases, your computer will work fine once you get your program running again.
Bugs are bits of code inadvertently written into the program, making it behave in unexpected ways.
Despite every effort manufacturers make to correct all bugs, there is no such thing as 100 percent bug-free software. Improper installation is another big cause of software problems. Note that failure to properly uninstall a program before attempting to reinstall it is probably the single largest cause of installation-related problems. But they are a real threat and something that I want you to know how to deal with. Fortunately, a number of good virus checkers are available.
