Why are virus writers so hard to catch?
"..."There does not seem to be too much diligence in some of these public Internet cafes with all these public terminals. You can go in, log on anonymously, slip in a floppy with a virus, spread it all over the world within a few minutes," said Vincent Gullotto, vice-president of antivirus research at Network Associates (NYSE: NET - news) and head of the McAfee Anti-Virus Emergency Response Team".
Or you could simply argue that they have every incentive to write more and more destructive viruses, and the 'security' industry has little incentive to stop them and put itself out of business.
Or you could follow the advice of the guy above, and end up here.
