Internet Security Setup

DISCLAIMER

On this page I will be discussing my Internet security setup. I am not making any warranties or guarantees whatsoever. Years ago I researched various sites and articles on Internet security, and found a mix that I was comfortable with. I highly recommend anyone who has a computer to do a thorough research on the topic, and come up with something they feel secure with.

INTRODUCTION

There are three types of softwares I think of to first install on a new computer: firewall, anti-spyware, antivirus. In addition, I would also install Mozilla Firefox, and I use it as my main browser.

I usually try to install the firewall before I even connect my computer to the Internet. But when that option was not available I settled for connecting online, and the first website I would visit is the firewall company's or http://www.download.com

I would then proceed to download and/or install my anti-spyware, antivirus programs, and an Internet Browser alternative to Internet Explorer.

Below are programs I use, have used, or would consider for use for each type. All of which are free (as of July 21, 2006), and unless noted otherwise are available at http://www.download.com:

Firewall:

ZoneAlarm

Anti-Spyware:

Ad-Aware SE Personal Edition

Spybot Search & Destroy

SpywareBlaster and SpywareGuard (http://www.javacoolsoftware.com/)

Anti-virus

AVG Anti-Virus Free Edition

Browser

Mozilla Firefox

Any questions as to the basic use of the programs are covered on the Help file, usually on the menu or appears as a ? icon on top of the program's window.

REGULAR UPDATE CHECKS AND MORE TIPS

I usually check for updates on each one of these programs every 2 or 3 weeks. Two programs that require an extra step once updated are SpywareBlaster and Spybot:

SpywareBlaster- once updated make sure to read the prompt, and activate Enable All Protection

Spybot- once updated go to the Immunize section and click the Immunize icon (+) to ensure that any Immunize updates are applied

Also, I try to ensure that my Windows Operating System, Win XP, is properly updated using Windows Update (Start > All Programs > Windows Update). Windows XP usually gets an update once a month.

Lastly, I primarily use Mozilla Firefox as my Internet Browser, and only use Internet Explorer when I cannot properly view a page.

My "Internet Security" setup thus include: Firewall, Anti-Spyware, Antivirus, and Mozilla Firefox. Of course regularly updating these programs, and the Windows Operating System is vital in maintaining their effectiveness. In addition, a very important preventative method is to only visit reputable websites. Watch what programs are being installed in your computer, and what emails or instant message links you click that leads to a website or installation of a program. Be aware, educated, and vigilant.

Solving Chemical Equations

I hate the guessing method in balancing equations. It's fine for simple equations, but at times it takes too much time without getting the actual results. It bothered me enough that I decided to look on the Internet for a different method. The best article was from wikipedia: http://en.wikipedia.org/wiki/Chemical_equation This page is my version of explaining the process in the article. ? CO + ? NO --> ? CO2 + ? N2 1. Instead of the ?, put in letters to represent the coefficients a CO + b NO --> c CO2 + d N2 2. Setup equality equations for each element in the equation. -list the elements involved in the equation -for each element, write its number of atoms in relationship to the coefficient in front of it, but differentiate between the left and right side of the equation by putting an equal sign in between. The last part should make sense in the example below For C, there is one C @ a on the left side of the equation, and on the right there is one C @ c. Thus, C: 1a = 1c We do the same for the other elements O: 1a + 1b = 2c N: 1b = 2d 3. Now using the equations above, solve for each variable in terms of a. a = 1a b = 2c - 1a c = 1a 2d = 1b -Looking at our variables, b and d are not in terms of a yet. c = a, thus 2c = 2a and we can use substitution on b b = 2c - 1a = 2a - 1a 2d = 1b, substitute b for a, so 2d = 1a , d = 1/2a 4. If all of the variables' coefficients of a are whole numbers then you now have your solution. If not, use the "problem" coefficient(s)'s lowest common denominator as the factor to multiply each coefficient by. Below are the coefficients we have, notice how d is not a whole number, and its denominator is 2. Use that number to multiply each variable's coefficient. a = 1a = 1*2 = 2 b = 1a = 1*2 = 2 c = 1a = 1*2 = 2 d = 1/2a = (1/2)*2 = 1 5. Substitute the numerical coefficients we just found in place of their respective variables in the equation. a CO + b NO --> c CO2 + d N2 2 CO + 2 NO --> 2 CO2 + 1 N2
