Essential Security Precautions for Your New Christmas PC

image You’ve been pretty good this year, (haven’t you?), so you just might get a new PC for Christmas  But, before you test drive this new machine, there are some fundamental precautions you need to take before you connect to the Internet.

Since you are reading, this I’ll assume that you are aware that there are some fundamental precautions you need to take before you connect to the internet with your new machine. I’m hopeful that you are reading this on your old machine.

Patch your operating system:


Download and install all available patches, and service packs – if applicable, by connecting to Windows Update. Security Gurus will tell you that 50% of unpatched, and unprotected systems, will be infected with malicious code within 12 minutes of being connected to the Internet. Believe it!

Install a Firewall:


Windows 7 comes with a vastly improved Firewall – substantially better than in previous versions of the operating system. Still, many techies consider third party applications more effective.

There are a number of free firewalls that are worth considering. The following are two that do the job particularly well. (Choose only one)

Comodo Firewall Pro:

The definitive free firewall, Comodo Firewall protects your system by defeating hackers and restricting unauthorized programs from accessing the Internet. I have been using this application for 18 months, and I continue to feel very secure. It resists being forcibly terminated and it works as well, or better, than any firewall I’ve paid for. This is one I highly recommend. Amazing that it’s free!

PC Tools Firewall:

I’ve been running with PC Tools Firewall for a few months, first on Win 7 Beta, and now on Windows 7 RC, and in this short time period I have been impressed with its performance. It installed easily, set up quickly, and has not caused any conflicts with my machine despite my sometimes esoteric running requirements.

The default settings are well thought out, and provide excellent protection for less experience users – and despite the hype put out by the IT industry, most computer user can be classified as having limited system experience.

Install anti-virus software:


There is no doubt that an unprotected computer will become infected by viruses and malware within minutes of first being connected to the Internet. There are many free versions of anti-virus software available, and the programs listed below have a well justified reputation. (Choose only one)

Avira AntiVir Personal:

This anti-virus program offers comprehensive protection with an easy to use interface. In the time that I have been testing Avira I have been impressed with its performance, and I have come to rely on it as my primary anti-virus program on an XP Pro system. I highly recommend this one.

Panda Cloud Antivirus:

I’ve been testing the Beta version of Panda Cloud Antivirus since the end of April 2009, off and on, and I’ve been pleasantly surprised with it’s performance, particularly the light use of system resources. This application is definitely not a resource hog, and I found it outstanding at recognizing and blocking malware threats.

Install Anti-spyware and Adware Software:


It’s not only a virus that can put your computer down for the count, but a multitude of nasties freely floating on the Internet. Listed below are a number of free programs that offer very good protection against malware.

Microsoft Security Essentials:

I’ve been running Security Essentials as a tester for months on my Win 7 machine, backed up by my usual, on demand, security applications and I’ll state, without any hesitation, I’m impressed. I highly recommend this free application.


Many software reviewers consider Ad-Aware Free as the best free adware remover available. It does a relatively good job of protecting against known data-mining, Trojans, dialers, malware, browser hijackers and tracking components. The only downside with the free version is, real-time protection is not included.


ThreatFire blocks mal-ware, including zero-day threats, by analyzing program behavior and it does a stellar job. Again, this is one of the security applications that forms part of my front line defenses. I have found it to have high success rate at blocking mal-ware based on analysis of behavior. I highly recommend this one!

Internet Browser Protection:


Web of Trust (WOT):

WOT is a free Internet Browser add-on (my personal favorite), that has established an impressive 4.5/5.0 star user rating on CNET. WOT tests web sites you are visiting for spyware, spam, viruses, browser exploits, unreliable online shops, phishing, and online scams, helping you avoid unsafe web sites.


SpywareBlaster prevents ActiveX-based spyware, adware, dialers, and browser hijackers from installing on your system by disabling the CLSIDs (a system used by software applications to identify a file or other item), of spyware ActiveX controls.

A secondary but equally important function offered by SpywareBlaster, is its ability to block spyware/tracking cookies and restrict the actions of spyware/adware/tracking sites in Internet Explorer, Mozilla FireFox, Netscape, Seamonkey, Flock and other browsers.

If you are now on the Internet, and you have not yet taking the precautions as outlined above, you are extremely vulnerable and it is critical that you take the following precautions:

Stop surfing the Web and patch your operating system. Only then download the protective software as noted above, or software that you are familiar with that will do an appropriate job of protecting your computer.

Do not visit any other websites until you have done this.

Additional security precautions:

Establish a password for the administrator account. Only you should have access to the administrator settings on your PC.

Create a new password protected user account. Using this account for your general day-to-day activities adds another layer of protection to your computer. A user account does not have the same all-access permissions as your administrator account, and in many cases this extra layer of protection will restrict malware from gaining a foothold on your PC.

Good luck and safe surfing.

  1. oops, have a problem with your first paragraph;

      Thanks Tony.

      To much holiday cheer last night I think – I dropped a sentence in the posting process!

      If you ever decide to take up proofreading, you’ve got a job here. LOL!

      Merry Christmas,


  2. What about putting a router in between the new computer and the internet? It will let you connect to the internet and run windows/Microsoft update and be fairly safe from stuff like worms because you’ll have a router tossing out all the garbage being spewed over the internet before it hits your computer.

    Hey Bill,

    Have a great Christmas. Thanks for all your great work here, I’ve found tools on your blog that now are part of my security arsenal and do a great job.


  4. Thanks, those are some great softwares you present here. You have a very nice website, happ Christmas

  5. Great post, you lay it out neatly.
    Not sure if any of the anti-malware programs suggested has an IP blocker function (I know Spybot does it with the hosts file and Malwarebytes needs the full version to do it). The first downloads and patches can be safely taken from trusted sites only with the firewall activated only – so no need to freak out at the idea of going online unprotected by AV software. Happy holidays!
