Trying to understand file.exe flowbit

Hello,

I'm currently running Snort 2.9.3.1 with Pulledpork to manage rules, have
an active Subscriber subscription to VRT rules, and am running a 'balanced'
policy with a number of rules enabled and disabled in PP.

My problem is that currently sid 15306 is about 43% of my total generated
alerts and I'd like to turn it off. However, 15306 sets the file.exe
flowbit. Looking through the rules I noticed a number of other sids also
set file.exe (including 11192, 16313, 16425, 21908, 21909, and 23725 but I
may have missed a few others). If any of those other rules set file.exe do
I still need 15306 to be enabled for all of the rules that check for the
file.exe flowbit?

Thanks!

Bobby
