After a fortnight of extraordinary type,

题目：

After a fortnight of extraordinary type, the much-feared computer virus that was supposed to strike the globe’s hard drives last Friday simply fizzled. So many warnings were sounded that most computer owners either fed anti-virus programs into their systems or refused to turn the power on during the dreaded M-day. They dodged one disease, but more strains are on the way. The eponymous Friday-the-13th virus is due to strike this week, and the Maltese Amoeba may detonate on March 15.

Who creates these things? A disproportionate number seems to originate in Bulgaria or Russia, where writing the smallest, most elegant virus programs has become a matter of quirky pride. Viruses are transmitted either by shared disks (as was Michelangelo) or over telephone lines. The virus program hides in a computer until, activated by a date, time, or some other trigger, it springs to life. The most common virus, Stoned, makes your screen announce: “Your computer is now stoned. Legalize marijuana. ” (Regardless of your politics, you don’t want this one around; it can damage your files inadvertently.) Solution: either keep your computer isolated—no trading disks, no on-line communication—or else install one of a dozen or so commercially available anti-virus programs that detect and delete the little time bombs. If they can come up with a virus that is hidden, will they next try to extort a business?—as in, pay me $1 million or my virus will destroy your system.

In the meantime, money is being made by firms selling anti-virus programs. Egghead software stores logged a 3,000 percent jump in anti-virus sales. Was the threat overblown by the companies that make millions selling anti-virus software? Thanks to the media blitz, no one will ever know what might have happened—an unallied number of computer owners discovered and deleted Michelangelo before it was supposed to strike—on the artist’s birthday.
