Defining Hacker
There are many reasons why people hack. Some do it for fun, profit or to prove a point.
Hacking is simple enough that a 9 year old can do it.
Software Flaws / Updates
Are the prime reasons computers are compromised
Anti Virus
Protects against viruses
A virus is self replicating and tries to damage a computer
Anti Malware
Malware is software that’s primary purpose is not to damage a computer
Malware generally tries to collect information about a user, or tries to force a user to visit sites or buy products.
Hardware firewalls are built into routers
Software firewalls are installed onto your computer
“Security” Suites
Security Suites can be worse than hackers — We have met the enemy and he is us.
If you use an account other than ADMINISTRATOR or ROOT when you normally use your computer you will be more secure.
Site Advisors
Warn you if you are going to an “unsafe” site
Web Browsers
The Problem with Internet Explorer is that is does more than just browse the Internet.
Firefox and Chrome are better but still have problems

    Great boilerplate, bringing the heat to the newbs.

  28. Liberty DIY says

    Sounds ridiculous, but it is possible that updating software and anti virus software is causing more problems than viruses and hacking, unbelievable bloat right. First step if you are having problems with your computer, reinstall your OS. Keep your data off the C drive so you can reinstall easily.
