You can check the code in the src/ directory of the rules tarball.

Thanks, how do I see the compiled code which is the root cause of this false positive I'm seeing?
I'm seeing an Acrobat Reader executable being pushed out causing alerts for this rule.

A similar question came up the other day. This is a gid:3 rule, a Shared Object rule. The detection part is actually a compiled code and what you see is the rule stub. The flowbits is set by another rule to make sure that the detection alerts on executable files.

Hello list

Could anyone shed light on the rule 39379?

I can't see any content matching, it simply alerts on any file that is an executable being downloaded, is that right?
If so, what has this got to do with Norton Antivirus?

Many thanks in advance.
