I am also and owner of (several) N900 since 2012.

I also worked for an anti-virus company for 15 years in the past, most of that in the virus detection engine development team. The interaction with the guys in the virus analysis lab was close and frequent, with requirements and feedback flowing both ways.

So one could say that I have at least some experience with the a) N900 and b) viruses.

And I can confirm with full confidence that Xkcd got it just right:
