A reasonably computer-savvy and cautious person should really never get one, and catch it if they do.

There is no known cure for stupid and apathy.

But that’s the real trick isn’t it? These viruses count on people not bothering to have & run anti virus software or keeping it up to date. Its the lazy, irresponsible, ill informed and generally computer ignorant unwashed masses that allow these thing to get to infection numbers like 9 million and there by cause such havoc for the rest of us! Most of them will not care or even check until after they are infected and probably better than half will remain clueless as to their infection until informed by a third party.
Even worse yet MOST of those people will not learn anything form the experience and will repeat it again & again to the detriment of the rest of us.

Good article. Sophos’ Conficker removal tool can detect and remove all variants of the worm/virus.

As long as people run these tools it should stop any serious outbreak.
