It is almost impossible to give an exact number of viruses
present at any moment because new viruses come into the
field almost everyday. Furthermore, different anti-virus
researchers use different criteria to decide whether two
viruses are different or same. Some call them different
if they have slight change in their appearance. Others
group the viruses in families and count closely related
variants as a single virus.
Speaking loose, more than 40,000 viruses exist today.
