Are Computer Viruses Spread By The Media?

computer-virusIf you believe what you hear in the media, there are an awful lot of viruses going around. No, I’m not talking about the make-you-sick kind of virus, though they get plenty of airtime too, especially the swine flu. I’m talking about the kind of virus that enters via your Internet connection rather than your nasal passages.

What the mainstream media often don’t tell you – at least, in most radio and television newscasts and in the crucial headlines and opening paragraphs of newspaper articles –  is that many of these “viruses” are not viruses at all.

What Computer Viruses Really Are

The main reason the mainstream media always are in alarm over viruses is that they tend to call any malicious computer program a virus. In reality, there are at least eleven distinct types of malicious software, or malware, commonly affecting computers today. The most common of these are worms, trojans, and spyware.

So, what’s the difference between computer viruses and the other types of malware? The difference is that computer viruses are just about the only ones that regularly shut down computers and cause other obvious damage. The most common of the other kinds of malware (worms, trojans, and spyware) are often only detectable with a special scan.

The Real Danger of Computer Viruses

If the other types of malware are so unobtrusive that they can only be detected with a special scan, then what’s to worry about? For starters, these programs are called malicious for a reason: they are designed to cause some kind of damage, if not to your computer, then to someone else’s.

Worms are most famously used to damage, destroy, or disrupt other computer networks than the one on which the host computer is located. For instance, worms have been used by website owners to shut down rival websites by sending overwhelming numbers of requests to the computer that hosts that website. Worms have also been used to send out viruses to other computers, often without infecting the host machine – after all, what would it benefit the worm to shut down its host computer?

Trojans, in turn, are often used to insert worms and other malware on your computer, even if the trojan itself does no damage.

But even if you don’t care what happens to anyone else, you should still be concerned about one kind of malware: spyware, a kind of malware that, true to its name, collects data from your computer and sends it back to a remote host.

Most spyware is only interested in monitoring your internet usage so it can tell other programs, called adware, what advertising to popup on your computer. However, there are criminal spyware programs that steal financial data, or perform a thorough identity theft. Don’t think you have personal or financial data on your computer? Some spyware programs contain a keylogger, which is a program that copies whatever you type, usually in order to snatch passwords. Even if you keep no financial information on your computer, if you ever buy anything over the web, the keylogger would allow its owner to buy stuff using the same information you typed in to buy stuff yourself.

Why Blame the Media?

Given the danger of all these different types of malware, isn’t it a good thing that the mass media are becoming hysterical about it? And can’t they be forgiven the sloppy reporting of calling trojans, worms, spyware, and other malware “viruses”?

No, no, no.

This is a classic case of bad reporting doing more damage than no reporting at all. In this case, the damage bad reporting has done is to promote a common myth that goes something like this: “The only malicious software is a virus. Viruses damage your computer. Therefore, if my computer is working OK, my computer has no malicious software. I only need to scan my computer for problems when there is a sign of problems.”

Thanks to this myth, many people complacently let their antivirus software go months out of date, not wanting to be bothered with scheduling an automatic update and scan. Just as bad, many people don’t have any extra software to combat the other types of malware that may not be covered by antivirus software.

In fact, it’s not uncommon for people who have found malware on their computers after a scan to say, “but I never had malware on my computer before!” But how would they have known if they had never scanned!

Until the biggest mainstream media – and especially television – start educating the public about the need to have their computers automatically scanned at least daily, the world will continue to have major, drawn-out problems with malware that could have been wiped out as soon as soon as the anti-malware software makers discovered it.

And until that day, the mainstream media will have many more opportunities to run hysterical stories about “viruses,” thereby forcing them to sell more newspapers and broadcast to even larger audiences of people who suck at the information trough yet somehow never become full.

Have you ever had a virus on your computer?

I’m one of the reactive people who don’t bother with antivirus programs. One of the reasons is that I hate how much it slows down your computer, especially at start up. I have been using Linux Mint for about 6 months and haven’t looked back. Although there are some viruses for linux, it is a tiny tiny fraction compared to the number for other OS’.

Wow, I’m glad to see that you’re running Linux, cause when I first saw you didn’t bother with antivirus software I almost fell down my chair 🙂

I feel the same way like you – I’m using a Mac and even though there might be a very few virusses/trojans/whatever, it’s not really worth it (for me) to run any antivirus software.

Love your point in this post.
Recently, virus and scam links are spread via popular social media sites especially twitter and facebook. People there use shortened urls which easily hide the real links. Once the accounts are hacked, the bots still send the poisonous links to others in the list and so far. Therefore, malware are so easy to spread these days.

That’s true, unfortunately. But I think some (or most?) of the short-url services today are clever enough not to redirect the user if the final URL will be harmful. Of course it might require some people to get hurt first before the URL will be flagged (maybe in Google or similar). But it’s better than nothing, at least.

Mostly customers won’t bother much about antivirus/malware until their systems are attacked. Once they do, they hope the product purchased can solve ALL the problems, forever and ever. Yes, no updating required. It has been a habit to educate customers don’t trust all the links, even they are from friends; update constantly etc. If I was still in my previous work place, I’ll print out this post, enlarge it, paste it somewhere visible.

You really think that people would have bothered reading all that, if they don’t bother protecting their computer? 😀

Nah, they probably need some kind of “funny picture” that will teach them what might happen – or they just have to lose all their family photos once and they’ll never be without antivirus software again.
