The only virus that I know of written in Perl was SelfGOL, written by TheDamian. And very few people out of the Perl community have ever heard of it.

By contrast the list of viruses written in Microsoft's VB is extremely long, and includes a substantial fraction of the best known and most costly viruses in history. (Can anyone say Melissa and derivatives? I knew you could.)

However - still - members of the general public have no clue that most of your virus concerns are eliminated in one stroke by removing Outlook/Exchange. And a good portion of the remaining commonly exploited holes are removed by switching away from IIS.

Ah well. It just goes to show that even in the Internet age, the Big Lie still works just as well as it did in Stalinist Russia...
