"You see, there is no way to write a program that can predict the potential behavior of other software in such a way that it will not interfere with normal computer operations. So, the only way to find a virus is to already know what it looks like, and go out looking for it. There are several major problems with this approach. First of all, the virus has already struck and done some damage. Two it has already infected other software and will continue to spread. Three, a program must be written to defeat the specific virus usually using a unique signature for each virus, and the vaccine for the virus must be distributed to the computer users. "This process can take from three to twelve months, and by the time the virus vaccine has been deployed, the very same virus has been changed, mutated, and the vaccine is useless against it. So you see, the Virus Busters are really wasting their time, and worst of all they are deceiving the public." Dr. Sternman com- pleted what he had to say with surprising force. "Doctor Sternman," Senator Rickfield said with disdain, "all of your theories are well and good, and perhaps they work in the laboratory. But isn't it true, sir, that computer viruses are an overblown issue that the media has sensationalized and that they are nothing more than a minor inconvenience?" "Not really, Senator. The statistics don't support that conclu- sion," Dr. Sternman said with conviction. "That is one of the worst myths." Nancy Deere smiled to herself as the dorky college professor handed it right to a United States Senator. "The incidence of computer viruses has been on a logarithmic increase for the past several years. If a human disease infected at the same rate, we would declare a medical state of emergency." "Doctor," implored Rickfield. "Aren't you exaggerating . . .?" "No Senator, here are the facts. There are currently over 5000 known computer viruses and strains that have been positively identified. Almost five thousand, Senator." The good Doctor was a skilled debater, and Rickfield was being sucked in by his attack on the witness. The figure three thousand impressed everyone. A few low whistles echoed through the large chamber. Stupid move Merrill, though Nancy. "It is estimated, sir, that at the current rate, there will be over 100,000 active viruses in five years," Dr. Sternman dryly spoke to Rickfield, "that every single network in the United States, Canada and the United Kingdom is infected with at least one computer virus. That is the equivalent of having one member of every family in the country being sick at all times. That is an epidemic, and one that will not go away. No sir, it will not." Sternman's voice rose. "It will not go away. It will only get worse."
