Each company will use a different scale, but they all will likely be the result of a weighted score considering:

  • if it escalates itself
  • the damage it causes
  • if it disrupts communication
  • how hard it is to block/remove
  • how easy it is to get infected
  • how it gets passed on to other machines

Here is a similar scale: http://reviews.cnet.com/4520-6600_7-6274750-1.html

Symantec rates malware based on reputation and behavior classification and doesn't use a 'low-high' scale anymore.

Thank you, behavior classification sounds interesting, I'll have to check that out. –  rd42 Nov 8 '12 at 13:25
