Not at all. This question is virus pundits' pons asinorum: If they can't think past this fallacy, don't even try to reason with them, as they're hopelessly mired in rationalisation.
The speaker's supposition is that virus writers will (like himself) ignore anything the least bit unfamiliar, and attack only the most-common user software and operating systems, thus explaining why Unix viruses are essentially unknown in the field. This is doubly fallacious: 1. It ignores Unix's dominance in a number of non-desktop specialties, including Web servers and scientific workstations. A virus/trojan/worm author who successfully targeted specifically Apache Linux/x86 Web servers would both have an extremely target-rich environment and instantly earn lasting fame, and yet it doesn't happen.
2. Even aside from that, it completely fails to account for observed fact: Assume that only 1% of Internet-reachable hosts run x86 Linux (a conservative figure). Assume that only one virus writer out of 1000 targets Unixes. Then, given the near-instant communication across the Net that at this writing is blitzing my Linux Web server with dozens of futile probes for the Microsoft "Nimda" vulnerability per second, the product of that one virus writer's work should be a nagging problem on Linux machines everywhere -- and he'll be working very hard to achieve that, given the bragging rights he would gain. Yet, it's not there. Where is it?
The answer is that, for various reasons discussed in prior essays, such code is very easy to write, but completely impractical to propagate. And likely to remain so.
