Similarly, What brand is the safest car?
Obviously the one you don't have an accident in. A recent article in Dr Dobbs reiterated the sentiments that Windows is the most targetted o/s. It also went on to say the Linux had some severe security holes also but as it is normally not targetted by the average virus that there is the perception that it is more secure. It also went onto say the Vax VMS is probably even more secure as hardly any computers run it nowadays and the virus writers simply would not target it.

It's interesting how Microsoft gets the blame trather than the third parties that write the virus. If we cured the root cause (ie the virus writers) then the security holes would not be an issue. Next time I get a nail in my tyre(tire) I'll curse the tyre manufacturer for not making his tyres nail resistant rather than curse the builder or whoever allowed his nails to be dumped on the road.

Also, why doesn't my ISP block the sites that are known to probe for unsecured computers?
