I have used the Cyberkit 2.2 rule seems to pick up Welchia. I do get
some false positives but if I get more than 20 alerts within a short
time than I know that it is Welchia.

The reason I ask is that I saw on arachNIDS that the rule was a little

I just started using snort. In order to use this rule, do I just add
to the virus.rules file and enable the rule in snort.conf?
If I should start with something a little more simple, let me know.
