Name five computer viruses

There are three main types of viruses, complex, rod and geometric. There are many more but all the others are either subtypes or strains of those three or cover a very small number of viruses. However if you want to know how many different viruses there are the answer would be in the billions.

Viruses can be categorized on the following bases:

• On the basis of the type of nuclear material they carry:
• • a) DNA virus
  • b) retrovirus or RNA virus
    

• On the basis of morphology (shape):
  
• • a) helical
  • b) Complex
  • c) Enveloped
  • d) Icosahedron
