Helping people with computers... one answer at a time.
Did you ever wonder how you'd know if your firewall is doing the job? (You are using a firewall, right? No? Go here. Now.) In most cases you wouldn't know you didn't until it was too late - after an infection or compromise of some sort.
Steve Gibson's an internet security guru, and his site Gibson Research is coming to be known as the place for security tests and related utilities. His popular "Shield's Up" is an online test that will tell you exactly what your firewall may, or may not be protecting you from. He's also the author of what is arguably the best disk maintenance and recovery tool available: SpinRite.
I really have only two qualms about Steve and GRC:
the site can be a little difficult to navigate
Steve tends to use what I'd consider to be fairly alarmist wording. Things typically aren't as awful as his words might lead you to believe.
But don't let that get in the way ... in particular, visit that "Shield's Up" security checking tool. It's well worth a few minutes of your time to see just how vulnerable you may be. If you don't have a firewall, you may find yourself running out to get one soon after you run the tests.
SpinRite is also available at grc.com - it's a low level disk maintenance and recovery tool that, while not free, operates at a level lower than any other tool on the market and can often repair and recover hard disk contents resulting from a variety of failures.
Finally, Steve Gibson and Leo Laporte (the "other Leo") are the voices behind the incredibly educational and popular Security Now weekly podcast, which you'll also find archived on grc.com.
Shield's Up, SpinRite, Security Now, a number of other free and useful utilities ...
Grc.com - I recommend it.
