# Glad that you found the source of the issue. Just keep in mind that manual changes to .rules files, i.e.: 
deleting/commenting rules, will be overridden by the next rules update. Just a wild guess here, but from what you said 
you may have these two rules in multiple .rules files, which eventually are included in snort.conf. When running Snort, 
does the startup messages indicate anything about duplicate rules? Just to further verify.
