问题     Can computer viruses ever be a force for
progress? In the wild west of the online world, the
archetypal(原型的) baddies(坏人) are computer
viruses and worms. These self-replicating programs
are notorious wreaking havoc(破坏) in the systems                S1.______
of unwary users. And, as in the west, not all gunslingers        S2.______
wear black hats. Some viruses writers wish                       S3.______
their fellow users well, and have been spreading viruses
that are designed to do good, not harm.
    Cheese Worm, which appeared a few weeks
ago, attempt to fix computers that have been compromised         S4.______
by the Lion Worm. The Lion Worm is
dangerous. It infects computers that use Linux                   S5.______
operating system, and creates multiple "backdoors"
into the infected computer. That then e-mails information        S6.______
about these backdoors to people who wish
to misuse that computer for nefarious purposes as                S7.______
"denial of service" attacks on websites.(Such attacks
bombard a site with so many simultaneous requests
for access that it comes out with its hands up.)
    The notion of "good" viruses may sound novelty;              S8.______
but, according to Vesselin Bontchev, a virus expert with
Frisk Software International in Iceland, it is not.
Also, early attempts to create beneficial viruses—              S9.______
for example, programs that compressed or encrypted
files without asking a user’s permission—resented,              S10.______
because they represented a loss of control over a user’s
computer, and a diversion of data-processing resources.
Inoculating computers against infection sounds like a
good idea, but fails because any unauthorised changes
are suspicious.
