As far as I'm concerned, my computer is a sacred place.  It's where I store some of my most prized documents, pictures, files, and my daily personal journal.  Therefore, anybody getting into my "space" without my permission is trespassing bigtime!

Sadly, there are people who don't hold the same opinion of my stuff.  They want to steal it, ruin it, mess it up, mix it up, and otherwise intrude.  Hackers want to break into my system and use whatever information they find.  They'll often create and release viruses that alter or scramble the hard drive or files so that they can't be used.  Some viruses and "worms" are so bad that they completely wipe a hard drive clean and much valuable information is lost forever!  Spyware allows other computer users to see what you're working on from their remote location.  It's like having a surveillance camera looking over your shoulder.  To protect against viruses and spyware, purchase a complete anti-virus, anti-spyware software that scans your computer daily and removes unwanted or dangerous threats.  It will also alert you to possible threats when you visit any website or try to download software.  To keep hackers out of your system, don't use passwords related to your likes, passions, or lifestyle.  Hackers look for the most logical links first.

Now frauds and scams are totally different.  There are always dishonest people out there trying to take your money from you.  They offer products or services that either aren't what they say they are, or they take your money and never deliver.  They "milk" innocent people out of millions of dollars every year.   The best way to avoid them is to never answer an unsolicited email, never give out your personal information, and research the product or company before you buy from them.
