This is the MOST BORING book I've ever read. Whoever read it for publication obviously knows NOTHING about computers. He constantly repeats himself and really says NOTHING---other than "don't download from the internet and don't share files". And it's obvious he knows nothing about viruses either. Doesn't give any description how to prevent them---other than buying virus protection software, which most computers come with now. By constantly repeating everything at the beginning and end of each chapter with litte content in between, the book could of been scaled down to 10 pages of non-repetitive words from the 350. It's ONLY redeeming quality is a couple C++ programs he copied from other people and some of the websites he mentions. Other than that, it deserves a rating of "ZERO".
