Maintaining a Safe Computing Environment

So, how do we protect ourselves?  There are quite a few things we can do:

• First never go on the internet without a zone protecting software such as Zone Alarm.  This program places a "firewall" between your computer and the rest of the internet.  You choose which programs can access the internet, but most importantly you choose who can "enter" your computer FROM the internet.  The basic answer to this is "NO ONE", unless you are operating a Virtual Private Network or for some other reason need to access your home computer remotely.  If you are doing these things, your knowledge base is beyond the scope of this tutorial.  The few times allowing another computer "into" your zone might be when you have initiated a download or are performing updates to your operating system.  Even then, you generally download a small portion of the program and then the program asks permission to go "OUT" to the internet.  One of the best programs to use for this fire wall is a free version of Zone Alarm.  This version is FREE to private individuals and educational entities.  They do have enhanced versions which you might want to consider buying that combines the firewall, malware removal and virus removal tools.
• Personally, I also add more security to my systems by also incorporating a "hardware" firewall in the form of a router.  In my situation it is a wired solution, but there are many "wireless" versions available.  But, going wireless introduces another way for hackers to gain access to your computer (s), if not properly installed.
• Remove advertising and tracking "cookies" and other malware from your system after every session of surfing the net.  You will be amazed at how many entities are tracking your buying habits.  Or, at least, I am always amazed at who cares about my online adventures.  A Good FREE program is AdAware.  Like the Zone Alarm it is FREE for individuals, educational use.  Corporate entities should purchase the software.
• One of the strongest antiviral programs available is Avast AntiVirus and there is a home version of it as well that is FREE to the home user.  They do require that you periodically register the program, but there is no charge to you.
• Unfortunately, once malware or a virus have found their way onto your system you may well end up having to format the hard drive and reinstall every program from the operating system up.  It is a good practice to keep backups of documents you cannot readily replace:  pictures, letters, emails, anything that you cannot easily replace.
