Every once in a while we have anti-virus threads and 9/10 posts are of the type
"I've used XYZ and therefore it's good."
We need more than that, willingness to ditch whatever we're using based on actual reasons and we need to be weary of results posted on sites plastered with advertizements for anti-virus companies or otherwise connected to specific anti-virus companies.
So in short:
A. Is the advice being given by someone irrationally attached to a product (because
they've been using it for years and nothing happened
to them - therefore it's
the best.
B. Is the poster/site connected in any way to an antivirus company?
C. Are the definitions good? [Now there's a crucial point].
D: Are the ZERO DAY definitions good? One company will protect you on Day 1, another on day 13, so if you are testing on day 14, are their definitions equally good? That's a tough one to test but it has been done in the past.
E. Is the product free or pay-for? It is definitely a
myth that pay-for equals better. Some pay-fors are in the top few products and some free products can match or beat most pay-fors.
F: What are program's impact on computer resources?
So somebody's single personal experience tells you nothing.
Have they installed multiple products and tested multiple products and found actual differences? The best test I've ever done was after being in possession of a zero day Virus, quaranteeing it then installing multiple products, updating each with their latest definitions then unleashing the zero day virus. It was interesting to see how some detected it, some detected it only days later, some not even a week later. It was also interesting to see how some crippled the machine's performance in comparison to others, although top computer hardware today has advanced enough to handle that issue much better.
But still, I always say, tell me why I should switch away from what I am using and I will test your recommendation and switch away in a heart beat. We should not care about any anti-virus company for any other reason than the ones listed above.
