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.
