The variety of harmful viruses has been rising for over a decade; in 1993 solely about 10 % of viruses had been damaging, but by 2000 this quantity had risen to 35 p.c. Twenty to 30 new viruses are identified each day, and over 50,000 viruses have been detected and named since the early 1980s, when computers first turned integrated with the world financial system in massive numbers.

When my work computer gave the impression to be operating extra slowly than usual, I contacted my Help Desk to see if it was infected with a computer virus.
