Do You Really Need to Use Antivirus Software?

Pretty much everyone who has used a computer knows what anti-virus software is and what is does. In case you don’t know, anti-virus software basically gives you the potential to know if malware is trying, has tried, or maybe even has successfully infiltrated your computer system.

More and more people are starting to do away with anti-virus software because “they don’t need it”. Well I personally see anti-virus software as a tool…a tool that helps secure a computer system. When someone says that they “don’t need anti-virus software”, I think of the example that I gave to someone a while back on the Internet :

Let’s say you go around telling people that you don’t need to see a doctor to test for cancer, because you do not have cancer, nor will you ever get any. How do you have the potential to know that you do not have cancer, *if* you are not checked by a doctor? How do you know that you will *never* get *any* cancer at all? You don’t!

Your logic would not make sense in that situation because you are assuming something as fact, when *in fact* you are just guessing! The same applies to someone who says that they “don’t need anti-virus software” because they “know that they won’t get any malware” on their computer system or “I know that I am careful, hence I don’t need anti-virus software”. Sorry people but that logic just doesn’t add up!

Also it seems in my experience that many Linux users believe the idea that they won’t get any malware on their Linux systems, or at the very least they “don’t need an anti-virus” program running on their Linux system.

Like I have asked several times before, how can you have the potential to know if you have malware on your Linux system, if you do not run anti-virus software on your Linux desktop / server?

You are just guessing that you will not get any malware. You are even guessing when you say that you do not have malware currently on your Linux system!

Sure Linux has a lot less malware than Windows, but that is no excuse for ignoring security! 🙂

Also, I know that anti-virus software can have (and does have) security problems in of itself. However keep in mind that the companies that write the anti-virus software do update their software to fix security problems, so this is not necessarily a big deal (depends upon your situation).

Difference between Historical and Observational Science

Historical Science:  Non-repeatable, non-observational, non-testable   (e.g. the origin of the universe — Yes, the origin of the universe is historical science because no human was alive to observe it happening, nor could anyone repeat what happened even *if* they did observe it!)

Observational Science:  Is repeatable, is observable, is testable   (e.g. the study of medicine or the study of mechanics — You can actually observe things happening (e.g. mechanics), test and verify your findings.)

How good is pfSense?

About six months ago, I started using pfSense (uses FreeBSD) for my main router. I have been very pleased with it and will share a short description of my experiences with it.

Install Procedure

The install has two different paths. 1) a quick install,  or  2) a more detailed, custom install. I just went ahead and used the quick install (which works fine!). The actual installation took about 3-4 minutes to complete.

Initial Setup

After pfSense installs and reboots, you will have the opportunity to tell pfSense which network card is for your WAN and which network card is for your LAN connections. Also, Pf-sense will give you the opportunity to setup a VLAN if needed. I had no problems with this part of the setup!

Router Configuration (Part 1)

Well now you access (via a web browser) the newly install pfSense router using the default local (LAN) IP address pfSense assigned you. Once in, you will need to modify the router’s basic settings (e.g. WAN settings, LAN settings, etc.). Having your old router configuration with you, while setting up your new router helps a lot.

Router Configuration (Part 2)

Now you will need to modify pfSense’s settings to your needs! I installed Unbound DNS, a free DNS resolver. This allows me to resolve my own DNS queries, instead of relying upon my Internet Service Provider.

I setup a VPN (using OpenVPN) to my place of work. This has helped a lot in providing a safe and encrypted mechanism to transfer data between home and work.

I also assigned static IP addresses to different computers in the home. This helps when you are wanting things to “just work” and not having to worry about some IP changing and messing something up you were working on.

Overall View of pfSense

I am very pleased with pfSense. I have had almost zero trouble with it. pfSense handles many Internet connections well.

I would say that if you want a extremely powerful router, but do not want to shovel out the money to buy a Cisco router, pfSense gives you a really great alternative.

It is a really great solution available for free, and I would recommend that you try it out for yourself. Click here to go to pfSense’s home webpage.

Is the Linux Operating System Older than Windows?

I recently read online someone saying that “Windows did not come out as an OS til 1995”. Is this person correct?

First some background information about Windows.

The first Windows was Windows 1.0 that ran on-top of MS-DOS. It was released on 20 November 1985. The most popular ancient version of Windows people sometimes talk about is Windows 3.1 (released on: April 6, 1992), not realizing that there were versions of Windows before 3.1.

Microsoft has Windows NT (a stable, secure, really well done OS brand still being used by millions today; not MS-DOS based) that initially was released as Windows NT 3.1 on July 27, 1993. Windows NT has *no* MS-DOS underneath it (in other words, the Windows NT line has nothing to do with MS-DOS at all; people just think it does).

Non-Windows NT Operating Systems:  1.0, 2.0, 3.0, 3.1, 3.11, 95, 98, 98 SE, ME

Windows NT Operating Systems:   Windows NT 3.1, Windows NT 3.5, Windows NT 4.0, Windows 2000, XP, Vista, 7, 8, 8.1, 10

The first Linux came out by Linus Torvalds in 1991 (he uploaded Linux to a FTP server belonging to FUNET).

Technically Windows as an OS itself did not come out until 1993, however Windows *did* exist as an MS-DOS shell way back in 1985…long before Linux. Also, Windows 1.0 is seen as the first official Windows on the market. 

Linux first came out first as an actual OS in 1991. However Windows NT came out in 1993 (roughly two years after Linux; the guy’s statement about Windows being out as an OS in 1995 was off by two years).

So the answer is: While Linux (1991) is slightly older than Windows NT (1993), it really is not that big of deal since they both are good operating systems to get things done on, and seriously now, who would care anyway 🙂.


Update 10-04-2019:

I recently became aware of someone commenting on this blog post. The person said some of what I wrote was irrelevant to what the question was about. I would like to comment on that.

  1. I only mentioned the older, non-NT versions of Windows (e.g. Win98) to give background information to people who may not understand that there is more to Windows than XP (2001) and beyond. Of course you need to compare NT-based Windows OSes (not MS-DOS ones), otherwise you will have an apples-to-oranges comparison!
  2. Windows (as an operating system – Windows NT 3.1) did in fact come out in 1993. The guy who commented on my blog repeated the same misinformation about Windows coming out as an OS in 1995 😕. Seriously, this information is easily verified online.
  3. Unfortunately several people “up-voted” his comment, even though he gave wrong information about Windows NT and technically misrepresented my article.
