Why do I still get viruses even though I run anti-virus?


Why do I still get viruses even though I run anti-virus?

By Leo Notenboom

In this excerpt from Answercast #89, I look at why anti-virus software always lags behind the malware designers and how you can keep yourself safe on the internet.

Can’t prevent viruses?

Well, ultimately, you can!

So… There are a couple of different issues that I want to talk about with this question.

One is that there is no single anti-virus or anti-malware product that will absolutely catch every single virus or Trojan or other form of malware that’s out there. There just isn’t.

I have an article on that: “I run anti-virus software. Why do I sometimes still get infected?”

The virus race

The bottom line is that it’s ultimately a race. It’s a race between the different kinds of anti-malware technologies and the people who write malware. They come up with new techniques; new things to exploit and they push their viruses and malware out quickly, more quickly than software like anti-malware tools can be updated.

Imagine… it takes a little bit of time for something as complicated as an anti-malware tool to actually respond to tricky techniques with the complicated algorithms that they need to use to detect viruses – without detecting false positives.

So it’s a race. Malware is being created every day and anti-malware software is being updated. But it always (almost by definition) lags behind by some amount of time – during which you and I, and everyone else, are vulnerable to these new and increasingly more destructive pieces of malware.

  1. The writers of anti-virus software depend on virus writers in order to stay in business. If they get too good they will work themselves out of a job. Why souuld we trust anti-virus software writers when their continued existance depends on the continued success of their opponents.

    1. @Ronald Welch:
      So, do you recommend not using anti-malware programs? Malware writers are smart, and they know it’s a game of ‘catch up’. That certainly doesn’t mean that people shouldn’t defend against them.
      Your comments could address many disciplines. Would you suggest we stop seeking medical aid, because a world without disease would be a world without need of medical professionals?
      Now, if you’d like to discuss the moon landing hoax, please let me know.
