Help with Snort Processor

[Dan O'Brien via Snort-users <snort-users () lists snort org>]

Good evening all,

Looking for some suggestions to quiet (PROTOCOL-DNS domain not found containing random-looking hostname - possible DGA 
detected).  It goes off every time someone opens Chrome due to Chrome DNS prefetching. I disabled prefetching in Chrome 
but apparently it still does some things upon opening that cant be controlled in the settings. 

Browser Startup

Chromium automatically remembers the first 10 domains that were resolved the last time the Chromium was started, and 
automatically starts to resolve these names very early in the startup process.  As a result, the domains for a user's 
home page(s), along with any embedded domains (or anything the user "always" visits just after startup), are generally 
resolved before much of Chromium has ever loaded.  When Chromium finally starts to try to load and render those pages, 
there is typically no DNS induced latency, and the application effectively "starts up" (becoming usable) faster.  
Average startup savings are 200ms or more, with common acceleration over 1 second.

Looking for ideas beyond disabling the rule.  Thanks in advance. 

Thanks,
Dan
